A Stephen Hawking musical tribute was beamed directly at a black hole

The European Space Agency had its own special way of marking a memorial service for astrophysicist Professor Stephen Hawking. At the same time his ashes were interred at Westminster Abbey in London, the ESA beamed music featuring Hawking's famously synthesized voice towards the closest-known black hole.

Hawking was widely known for his work on black holes. He theorized that the phenomena emit a type of thermal radiation, which became known as "Hawking radiation." Hawking died in March at the age of 76.

Vangelis, who wrote music for Blade Runner and Chariots of Fire as well as the Cosmos: A Personal Voyage scientific docuseries, crafted the six-minute tribute piece; it features a message of peace and hope from Hawking. The ESA beamed the music towards the 1A 0620–00 black hole from its ground station in Spain. The black hole is around 3,500 light years away and "lives in a binary system with an orange dwarf star." When it eventually gets there, millennia from now, Vangelis' piece "will be frozen in by the event horizon," said Professor Günther Hasinger, ESA's director of science. Those attending the memorial also received a copy of the music.

"This is a beautiful and symbolic gesture that creates a link between our father's presence on this planet, his wish to go into space, and his explorations of the universe in his mind," Hawking's daughter Lucy said.

While the music and Hawking's voice will reach a distant solar system, on Earth his ashes have strong scientific company. They were laid to rest next to the graves of Sir Isaac Newton and Charles Darwin in Scientists' Corner, a part of Westminster Abbey dedicated to those who made significant breakthroughs. The memorial stone on his grave includes his equation that describes the entropy of a black hole, along with an image of one and an inscription reading, "Here lies what was mortal of Stephen Hawking."

Evernote cuts staff as user growth stalls

Image
Note-taking app Evernote has fallen on hard times of late, culminating in its latest spate of job cuts impacting 15 percent of its workforce (54 employees). CEO Chris O' Neil -- an ex-Googler who took the reins in 2015 -- announced the firings at an all-hands meeting earlier today, reports TechCrunch . In a message on the Evernote blog , O' Neill admitted he'd set "incredibly aggressive goals" for the company in 2018. He continued: "Going forward, we are streamlining certain functions, like sales, so we can continue to speed up and scale others, like product development and engineering." The layoffs follow an exec exodus just weeks ago and the company's recent brand refresh (complete with a refined logo and wordmark). But critics are more concerned about its product, especially the free tier, which they claim lacks the perks to...

The best air conditioner

After six summers of researching, testing, and recommending window air conditioners, we've learned that quiet and affordable ACs make most people the happiest—and we think the LG LW8016ER will fit the bill in most rooms. This 8,000 Btu unit cools as efficiently and effectively as any model with an equal Btu rating, and runs at a lower volume and deeper pitch than others at this price. Little extra features like a fresh-air vent, two-axis fan blades, and a removable drain plug help set it apart, too. The LG LW8016ER is a top choice for an office or den, and some people will find it quiet enough for a bedroom, too. If our main pic...

We won't see a 'universal' vape oil cartridge anytime soon

Image
Pre-loaded cartridges of cannabis concentrate are currently among the most popular means of consumption, and for good reason. They're discreet to use and easy to handle, a far cry from the dark days of 2016 when we had to dribble hash oil or load wax into narrow-mouthed vape pens by hand. But, frustratingly, an ever increasing number of oil cartridge manufacturers employ one-off design standards so that their products won't work with those of their competitors, thereby locking customers into proprietary ecosystems. We've already seen this with nicotine vaporizers -- which has a seen a massive rise in "pod systems" in the last few years, each outfitted with a unique canister and battery built to be incompatible with those of their competition. Is it too late for the burgeoning cannabis industry to set a universal standard for their product designs? ...
