Loving Dark Matter Rather Than Light


first_img(Visited 14 times, 1 visits today)FacebookTwitterPinterestSave分享0 There are two ways to describe dark things in science.  One is phenomena we know exist, even if invisible to us, because we can measure their effects with instruments (X-rays, infrared radiation).  The other is darkness as a placeholder for something not yet explained.  Cosmologists have been talking about “dark matter” for decades now, and “dark energy” since the 1990s.  Which category of dark ideas are they?  Whether scientifically valid phenomena or placeholders for ignorance, one thing is clear from recent articles: much more knowledge is needed.Still in the dark about dark matter (PhysOrg): “Dark matter, the mysterious stuff thought to make up about 80 percent of matter in the universe, has become even more inscrutable.”Variable dark energy could explain old galaxy clusters (New Scientist): Astronomers don’t even know what dark energy is, but now a Spaniard wants to twiddle with it.Little galaxies big on dark matter (PhysOrg): “Dark matter… It came into existence at the moment of the Big Bang.”  That’s how to talk with chutzpah about something nobody understands.Revolutionary new camera reveals the dark side of the Universe (PhysOrg): Now here’s an article about real stuff: ordinary electromagnetic radiation in the submillimeter range, being detected by the James Clerk Maxwell Telescope.Nobel Winners Keep Eyes on the Real Prize: Solving Dark Energy Riddle (Live Science): Three men got a lot of money from the Nobel Committee for “discovering” dark energy.  Now they want to discover what it is they discovered; “the force has yet to be directly detected, and the concept remains shrouded in mystery.”Could dark matter not matter? (PhysOrg): Some Italian has come up with a way to explain the rotation curves of galaxies without appealing to dark matter, but others are skeptical.Back to the dark ages (Live Science): A tiny smudge of red light boasts great things: “The newfound galaxy is so ancient that it and others like it may have played a role in the transition from the so-called ‘dark ages’ of the universe — a period before the first stars formed when a thick hydrogen fog permeated the cosmos — into the universe we see today.”  Remember that the early medieval period was called the Dark Ages by those who felt themselves enlightened.  Is history repeating itself?This is a taste of the quandary over dark things in space.  To some, dark matter must be real, because otherwise clusters would fly apart and galaxies would spin out of control.  Dark energy must be real or else we cannot explain the brightness of distant supernovae.  To others, appeals to unknown dark things sounds mysteriously like some of the occult forces ditched by scientists in the past, like phlogiston, animal magnetism, and caloric.  Time will tell if and when the light of knowledge will overcome the darkness.How long do you give scientists to propound occult forces?  Another decade?  Another century?  A millennium?  If there is no time limit on verifying these things, then science has become indistinguishable from magic.  Mesmer would feel vindicated.Dark matter is the flubber of astronomy.  Nobody knows if its MACHO or WIMP-y, nobody knows why it is there, and nobody knows its origin or destiny.  All it does is make consensus theories work.  OK, astronomers, maybe you’re right; there is dark matter and dark energy out there.  We’ll grant a little more time for science to try to explain this stuff, but we’re not going to fall for the flubber theory forever.  Cosmologists: if you don’t want angels, demons and intelligent designers in science, then stop giving us your own version of the occult.last_img read more


A sleeping beauty discovered


first_imgKhanyi MagubaneI am a fully fledged and proud citizen of the concrete jungle.The noise pollution, bumper-to-bumper traffic, bright city lights, the fast-paced life, a quick lunch here, a Long Island ice tea cocktail after work with a friend, which makes way for a book launch at 6pm and soon after that I have to dash for a dinner appointment at 8pm, get home around 10, check e-mails, Facebook and send messages, watch a bit of late-night TV and, before I know it, it is after midnight on a work night. I am a self-confessed city-slicker.When I recently had to travel to East London, or eMonti as it is popularly known, for a friend’s wedding, I was initially excited at the prospect of leaving the home for a few days, but also panicked at the thought of being bored stiff in a small town where, I had been forewarned, nothing happens.When I arrived there I was pleasantly surprised to see my name scrawled across a board held by a smiling airport shuttle driver. In the car Luvuyo wasted in no time telling me East London was great fun, and I was going to enjoy it. I didn’t want to offend him, but I wasn’t so sure.Driving through the town and watching the locals going about their business, it was wonderful to reminisce about the carefree joys of small town living. Having grown up in Benoni, east of Johannesburg, I know it too well. Although no-one could ever tell, now that I’m completely urbanised.I decided I would put away my city snobbishness and explore the town.With only 880 000 residents East London, I discovered, boasts the best of rural, cosmopolitan and coastal beauty.This makes it easy for visitors with eclectic tastes like myself to find something appealing which, in this case, was a type of contemporary country living.First all, I learned that East London is not a town, as I had patronisingly called it, but is, in fact, the sixth largest city in South Africa.It has an interesting history. The British set up the city in 1836 as a military post, used during the frontier wars with the Xhosa people. The arrival of German settlers gave the area a much-needed economic boost.In 1873, East London was given town rights, which have since been upped to city status. Lying on the coast of the Eastern Cape province, it now forms part of Buffalo City, one of South Africa’s six metropolitan municipalities.It is South Africa’s only river port, set on both the Buffalo and Nahoon Rivers with the Gonubie River flowing around it.The local township of Mdantsane is reputed to be the second-largest in South Africa after Soweto.Many of Mdantsane’s inhabitants are people who were forcibly removed from what was then known as East Bank in East London. East Bank was a multiracial residential area, similar to Sophiatown in Johannesburg.When apartheid laws forbidding people of different races to live together came into effect, the blacks of East Bank were moved to Mdantsane, which was situated within the former Ciskei “homeland”.My home for three days in East London was a brightly red painted bed and breakfast guesthouse called the Red Pepper River Lodge.Overlooking the Gonubie River, the lodge was first class … a city slicker like myself finally felt at home. I had all the amenities I deem necessary for basic living: an ADSL line for internet, a wide flat-screen TV, a cellphone charger adapter, a feather-soft bed, clean towels and top it off, a beautiful view.By now, I had to admit it, I was relaxed. My host was gracious and left me to my own devices. I took the opportunity to swim and read an epic novel had I started many months ago, without considering time. I chastised myself for underestimating the calming effect this city would have on me.The day of the wedding, I was hungover and could hardly wake up. My cousin and I, accompanied by two good friends also attending the wedding, had managed to find a nightclub for “a drink or two” and some music. What was meant to round off a nice quiet dinner ended up being a nightlong extravaganza. We danced and drank until four in the morning to extremely good music – a mixture of new songs and old ones we hadn’t heard in a long time.At one point we decided to get disciplined and leave the club, but no sooner had we reached the car park than an old favourite tune came on and, without even discussing it, had to go back. We were hopeless and happy.Fast-forward to the wedding, there we were, the four of us standing outside the wedding chapel, hiding behind our sunglasses, feeling extremely tender and wishing for no sudden movements.After what seemed to be forever, our friends were eventually pronounced man and wife and we were only to happy for the reception to start so we could sit down and get some food and drinks into our dehydrated and famished bodies.On the flight back home the following day, I reflected on the past three days in East London. It felt like I had been there for a really long time. It’s funny how time can take on a different dimension when there is no pressure to be anywhere or do anything.I must spend more time outside of Johannesburg. I get so entangled in its hustle and bustle that I forget that there is a world of beauty in my country, waiting for me to discover it.There’s one thing I would change, though. I couldn’t find a single place that made Long Island ice tea in East London, so next time I’ll travel with a blender and a book of cocktail recipes.

Why YouTube’s Election Hub is Fizzling


first_imgTags:#marketing#web#YouTube Related Posts YouTube’s livestreaming Elections Hub received a swell of press coverage at launch, but come its first event – the Republican National Convention – the number of viewers was pitifully small. Do the low numbers result from the site’s lack of an adult audience, the difficulty of generating political interest among younger viewers, or ineffective promotion? Turns out, it’s all those things.YouTube partnered with big names for its Elections Hub: New York Times, Wall Street Journal, Al Jazeera English, ABC News, BuzzFeed, Univision, Larry King and YouTube favorite Philip DeFranco.  Every partner except for Buzzfeed, DeFranco and Al Jazeera English struggled to get 1000 views of its on-demand content during the RNC and leading up to its Democratic counterpart.    Low Viewership is No SurpriseThe low numbers aren’t surprising, according to a YouTube spokesperson who requested anonymity, as site executives didn’t expect the Elections Hub to be an overnight success considering the average age of the YouTube demographic is in their teens.“We’re very happy with how the Elections Hub is going in these very early days of the political cycle,” wrote the spokesperson in a statement to RWW. “It’s a long-term play that we hope is a great resource for people between now and November 6.” (The spokesperson added, “between live-stream views and views of on-demand video, there have been millions of views of the video on the YouTube Elections Hub since it launched on Wednesday,” but declined to provide specifics. It’s likely those millions are solely DeFranco’s.)Success with Internet-Savvy AudiencesThe list of highest-performing partners – Al Jazeera English, BuzzFeed and DeFranco –  makes sense as all three have a strong Web presence and appeal to a young Internet-savvy audience. DeFranco, who is a YouTube staple, generated at least 50,000 views per video (approaching 1 million on some). Millennials have left comments on his political videos along the line of, “I’ve never voted before, but now I think I will.” DeFranco fans swing Democratic, judging by the relative popularity of his videos, so high viewership of his RNC coverage is telling of his charisma.Conversely, YouTube Elections Hub shows that are meant to appeal to older audiences are failing. Some on-demand episodes of the Larry King Live Web show – presenting guests like Ben Stein and Tanya Acker –  have struggled to break 100 views.  Larry King has more than a million fans on Twitter, but apparently none of them are watching him on YouTube.Ineffective PromotionNonetheless, YouTube is committed to the project. “We’ll keep supporting the Hub with marketing and promotion on YouTube so that people know when major political moments are taking place, and they can check them out live,” the YouTube spokesperson wrote. This advertising strategy is problematic because YouTubers who are already on the site and interested in the election are clearly watching DeFranco’s coverage, and a DeFranco fan would not watch Larry King Live and may not have even heard of him. DeFranco heavily promotes his own shows and does not rely on the video site to promote his Elections Hub programming.Many Election Hub partners are not promoting their own YouTube coverage themselves, perhaps relying on the Google-owned company to do it for them.  Chaotic PartnershipsEven more confusing is the disunity: At press time, New York Times was livestreaming an interview with a pundit about the upcoming DNC through a video player on its own Politics front page, not through YouTube; visit the New York Times Election Hub page on YouTube and no stream of that interview can be found. Then there is a video of New York Times’ Jim Roberts interviewing BuzzFeed’s Ben Smith from the RNC floor on the impact of social media during this election cycle (President Obama on Reddit, tweets about Romney’s VP pick, Ryan) that has only 200 views. This video was not embedded on the New York Time’s site or even linked to BuzzFeed.Checking the ABC News and Wall Street Journal sites reveals a similar lack of promotional coordination.YouTube’s Election Hub won’t be the “long-term success” that the Google-owned company hopes for if the partners don’t bother doing the legwork themselves. Cross-promoting is social media (and YouTube) 101.  Why Tech Companies Need Simpler Terms of Servic… A Web Developer’s New Best Friend is the AI Wai…center_img Top Reasons to Go With Managed WordPress Hosting fruzsina eordogh 8 Best WordPress Hosting Solutions on the Marketlast_img read more


NLE Showdown: DaVinci Resolve vs. Adobe Premiere Pro — Text Effects


first_imgIn this NLE showdown, we compare the text and title generators in Adobe Premiere Pro and DaVinci Resolve — and there’s a clear victor.Earlier this year, I attended London’s VidCon with Blackmagic to demonstrate Resolve to the passing youngsters — or as many companies view them, the customers of tomorrow. Both Adobe and Blackmagic had a presence at the convention to promote their software to the up-and-coming content creators. While many young creators care little about 12-bit footage and RAW, they do long for quirky text functions. As I hear every weekend from my ten-year-old nephew, “Uncle Lewis, can you make me an intro for my YouTube channel?”So, how does each program measure up when examining title generators, built-in text effects, and pre-made presets?Resolve TextI will openly admit that I don’t like how DaVinci Resolve handles text. This is from my write-up Is DaVinci Resolve’s Title Generator a Hit or a Miss?:I love Resolve. It is, after all, a world-class color grading application, and the designers have made massive improvements with the NLE’s capabilities in 12.5 and in 14. However, the title generator is only standard NLE quality, despite a great-looking UI. It is great for simple location introductions, or to fade the name of an interviewee in and out. But for anything that is slightly creative, you’re better off working with a dedicated motion-graphics compositor.My main frustrations involved trying to do anything creative with text in Resolve. For example, in the still below, I have two text layers (because you can’t change the font size of one line in a simple fashion). One using the standard text generator, and the other using Text+. I’m able to move “The Beat” freely by simply selecting the text within the timeline viewer itself and moving the text to a new position. The PremiumBeat text, however, isn’t as easy. I must first select the text, then activate the transform tool, then move the text.Text+, which builds the text from a Fusion source, rolled out with Resolve 15, adding a number of creative controls with how the text operates — from animating the text with a write-on effect to rotating the text in z-space. Text+ also offers a lot more design choices by allowing you to adjust the shading of the color and the properties of the appearance, such as making the font appear as just a text outline.However (and again) frustrations arise when you realize that not all individual parameters have a reset function for when using Text+. And, even if you were to click Ctrl-Z to undo the action, nothing happens. It will only undo movement and font changes.From having to click through several menus to change specific properties of the text, to the tedious process of having to select the text on the track before changing the position in the timeline monitor, it’s not a fun process. We can’t forget what is perhaps everyone’s main grievance with Resolve and its text: when choosing a font, you don’t see a preview of the font’s design. You have to scroll through each font manually. (A Blackmagic representative stated in the Resolve Facebook Usergroup that this will be changing in the future.)While I have grievances with the simple text elements in Resolve, several 3D and 2D title presets were included with the incorporation of Fusion, last year. With these new titles, you can quickly drag and drop pre-made 3D custom titles to spice up your footage. Perfect for the content creator on-the-go.2D example:3D example:However, it does appear as if these presets are hard-baked into the software; therefore, you can’t customize the properties outside of the color elements.Many Resolve functions adjust with sliders rather than numerical inputs. While this isn’t inherently a negative attribute, I do find that the sliders respond a little too extremely. The slightest movement to the right can increase the text by 100 percent when you only want to move it 5 percent.Premiere TextIt’s no surprise that the company behind Photoshop offers an excellent text function in their editing software. A few years back, they removed the “add text object” and added a type tool similar to Photoshop. Being able to hit a keyboard shortcut (T) as opposed to opening the effects library, finding the title generator, and placing it onto a track is a lot more organic. And, if we want to talk about fluidity, the ability to just click on the text to move it is effortless. Of course, being able to adjust the size, font, and color of two lines of text in a single text object is a godsend. In Resolve, both lines of text would require separate text objects.Unlike Resolve and After Effects, Premiere doesn’t offer any built-in 3D text presets. As such, you would need to import them from After Effects. However, (and again) unlike Resolve, you can apply a vast number of video effects to the text object in Premiere — from transitions to the video effects themselves. In Resolve, if I were to apply a glow effect to a fusion title, it freaks out. (Although, it’s essential to note that you can apply effects to Fusion titles, but it has to be on the fusion page and added with the fusion effects.)If there’s one thing about Resolve that irritates me more than the text tool, it’s how it handles keyframes on the edit page. Whether audio, video, or text, keyframes are adjusted on the clip itself by opening the keyframe panel on the track. In Premiere, we have a separate window within the effects controls, which makes the process smoother and more efficient when animating text properties such as size or rotation.I’ve been trying to conjure something snarky to say about the type tool in Premiere, but there’s nothing to be said. It’s a simple, useful tool that’s easy to use. I haven’t edited in Premiere for over two years now, and despite pressing every incorrect keyboard shortcut, I was able to apply and animate the text quickly and with ease.I love using Resolve, and I think it’s the very best in many areas, however, text isn’t one of them. Despite not having custom presets or 3D text applications, Premiere wins this round for the simplicity of its text.Lewis McGregor is a certified DaVinci Resolve trainer.Looking for more articles on film and video editing?

Engineer murdered in suspected honour killing


first_imgIn a suspected case of honour killing, a 28-year-old civil engineer from Kerala was shot dead allegedly by his wife’s parents, who brought a sharpshooter with them to his house in the Jagdamba Vihar area here on the pretext of meeting the couple.The victim, Amith Nair, sustained bullet injuries on his neck, windpipe and chest and died of excessive bleeding. The parents tried to drag his pregnant wife, Mamta Chaudhary, out of the house, but they fled when she refused to leave.After the incident on Wednesday morning, Mamta’s parents have been absconding and the police have launched a manhunt to nab them. Amith’s body was cremated at Purani Chungi crematorium in the Sodala area here on Thursday in the presence of his relatives, friends and colleagues.Mamta, 30, belonging to the Jat community, had married Amith, a native of the Pathanamthitta town in Kerala’s Central Travancore region, two years ago, even though her parents were opposed to the match because of the caste difference. The couple settled down in Jaipur, where Amith was working as a civil engineer with a private firm.According to Mamta’s statement to the police, her parents had been insisting since her marriage that she leave Amith and return to them. Heated argumentsOn Wednesday, Mamta’s parents came to her house and after some heated arguments, called in a young man, who allegedly drew out a pistol and shot at Amith.As Amith collapsed on a sofa where he was sitting, the parents tried to drag Mamta out of the house. When the family raised an alarm and called the neighbours for help, they fled.Mamta is reportedly six months’ pregnant. Police said Mamta’s brother has been detained and a search launched to trace the absconding parents as well as the shooter. Barricades and check-posts were put up at several locations here on Thursday and on roads connecting the city with the national highways.People’s Union for Civil Liberties activists, who met police officers in connection with the case, demanded immediate arrest of the accused and action against two private hospitals which had refused to admit a heavily bleeding Amith. They also demanded that the State government pay a compensation of ₹1 crore to Amith’s family.PUCL State president Kavita Srivastava said Mamta, who studied in Mody University in Laxmangarh, was an intern with the organisation in 2014. She said it was high time the outstanding legislation on killings and crimes committed in the name of honour was enacted. “The couple shelter homes should also be established in all districts of Rajasthan on the pattern of Haryana,” she said.last_img read more


Three prisoners escape from police custody in Maharashtra


first_imgThree undertrial prisoners facing charges of dacoity escaped from police custody while being taken to Silvassa from Thane Central Jail in Maharashtra for a court hearing, an official said on Thursday. The accused, Jairam Dalvi (21), Ganesh Dalvi (20) and Martin Madha (30), were arrested last year by Silvassa police in the Union Territory of Dadra and Nagar Haveli and subsequently lodged in the Thane prison, senior police inspector Vilas Chowgule said. On Tuesday, while the prisoners were being taken for a court hearing in Silvassa, they complained of nausea and got down from the escort van on Mumbai-Ahmedabad highway near Vasai in Palghar where they gave police the slip, he said. The escort team later approached Valiv police here and lodged an offence against the accused under Indian Penal Code Section 224 (resistance/obstruction by a person to his lawful apprehension).The three prisoners were facing several cases of dacoity in Thane, Palghar, Mumbai and Gujarat, Mr. Chowgule said. A manhunt has been launched to nab the absconding accused, he added.last_img read more


Inside the worlds first Google Shop


first_img Google has launched what it calls a world-first smartphone experience in central London as the search giant looks to cement its presence on the high street.The Google Shop will see customers able to experience devices ranging from Nexus smartphones and tablets, Chromebooks, Chromecasts and Android Wear smartwatches as well as experience some of Googles other online services.The store allows customers to experience an interactive Google Maps experience on a large curved display, as well as creating their own Google Doodles on an interactive wall.The first Google Shop will be located in the Currys/PC World store on Tottenham Court Road with two similar installations planned for later this year. The shop is seen as a step-up from the current partnerships the company has in place with retailers in the UK where it has a limited presence within over 400 stores across the country.Retail storesSpeaking to IBTimes UK at the launch Google UKs marketing director James Elias said this was the biggest and boldest evolution of [Googles] store-in-store strategy to date but when asked if this was just a gateway to building its own standalone stores, Elias said the company had no plans along those lines.Apple announced earlier this week, on 9 March, that the company now had over 450 retail stores worldwide with aggressive plans to expand that number in China in particular. The company saw some 120 million people pass through the doors of its stores in just three months to the end of December, giving some idea of the revenue generating potential of the stores.Google is a very different business and while it has some hardware in the form of Nexus devices, these are built in partnership with the likes of HTC and Motorola and therefore the potential revenue gain for the search giant is not as instantly obvious as for Apple.Elias said that while the company was hoping the new Google Shop would help drive some revenue, it was as much about the experience, adding that the store wants to become part of the community with classes about how to stay safe online being held at the store in the future.

On Wednesday afternoon, investigators visited the flats in the building in front of which the blast took place on Tuesday. The owners and residents of the flats were also questioned.Later, CID officials measured the distance of damaged points from the blast spot. The shutter opposite the blast spot, which was also damaged, was opened. After opening the shutter it was found that a splinter had penetrated the shutter and damaged a showcase inside. Also Read – Speeding Jaguar crashes into Mercedes car in Kolkata, 2 pedestrians killedCID officials also looked for Close Circuit Television (CCTV) cameras present in the locality, to find out what actually happened. As no CCTV camera was available, sleuths turned towards the conventional method of enquiry by questioning the locals. According to CID sources, it is being suspected that the bomb which exploded on Tuesday was bigger than average socket bombs. Ammonium nitrate and acid were also used to intensify the blast. The cap at the bottom of the bomb was tighter than the upper one. As a result, most of the explosion was directed upwards, which cracked the windows inside the blast radius. Experts have collected samples and sent them for necessary examination.last_img read more


Store and clean your jewellery the right way


first_imgOnce you buy precious jewellery, it’s essential to store your expensive pieces in the right manner to avoid losing the sheen of the metal. Remove your jewellery while doing household chores, says an expert. Jewellery should never be tossed into a drawer or on top of a dresser as that will scratch and damage it. Following are some tips to help you protect your ornaments:*Diamond jewellery: To clean your diamonds, use a good quality jewellery cleaning solution that is easily available in the market. You can also mix some ammonia and water to clean your diamonds at home. You should always remove your jewellery while doing household chores like cooking, cleaning, dish washing. Also Read – Add new books to your shelf*Gold jewellery: If proper care is not taken, gold can lose its sheen and can become dull. Always clean your gold jewellery with a mild detergent, lukewarm water and a soft cloth. It is always advisable to keep your gold chains and bracelets in separate boxes as they can get entangled easily. Gold should be removed before diving into a chlorinated swimming pool as chlorine has a very harsh effect on gold. The chemical can weaken it.*Pearl jewellery: Just as the sun’s harmful rays can damage our skin, light and heat can affect a coloured gemstone’s durability and colour. Over time, and in excess, they can also fade or damage some gemstones, pearls and other delicate materials such as ivory which will bleach under extreme exposure to light. Always clean your pearls gently with a damp cloth, dry them off and store them in an airtight container. Never use plastic pouches to store your pearls, rather keep your pearls in a pouch that has soft lining. Always wear your pearl jewellery only after applying make-up. Also Read – Over 2 hours screen time daily will make your kids impulsiveKeep your pearls away from perfumes, make-up and hairsprays as they can cause discolouration. Never use baking soda or bleach to clean them. Do not swim when you are wearing pearl jewellery as chemicals in the water can destroy your precious pearls.*Silver jewellery: Exposure to chemicals can damage or discolour silver. Never wear them while swimming or doing household work.To clean your silver jewellery, use a phosphate-free detergent or just soap water. Rinse it off and wipe it with a soft and clean cloth. Never store your silver jewellery with any other metal as it tends to tarnish faster.last_img read more
