Astronomers Despair As SpaceX Starlink Train Ruins Observation Of Nearby Galaxies | Forbes

In the early hours of the morning today, Monday, November 18, two astronomers checked in on their remotely operated telescope in Chile, expecting to see images of distant stars and galaxies. Instead, they saw a train of SpaceX satellites crossing the night sky, a worrying sign of what might be to come for astronomy.

My first thought was how did they not see this coming, and second thought, for SpaceX there is no downside because eventually this forces astronomers to fully invest in off-world telescopes. Not satellite-based but more than likely Lunar Observatories and guess who offers to get them there, for a nominal fee of course.

Secretive energy startup backed by Bill Gates achieves solar breakthrough | CNN Business

Heliogen, a clean energy company that emerged from stealth mode on Tuesday, said it has discovered a way to use artificial intelligence and a field of mirrors to reflect so much sunlight that it generates extreme heat above 1,000 degrees Celsius.

Essentially, Heliogen created a solar oven — one capable of reaching temperatures that are roughly a quarter of what you’d find on the surface of the sun.

What Is The Most Important Element Of A Successful Startup? Hint, It’s Not The Idea, Team, Business Model Or Funding Dollars.

The number of self-employed people in the U.S. has grown by nearly 150,000 since 2014 to 8,751,000. This number is up from 8,602,000 at the end of 2016. That data, from the Bureau of Labor Statistics, is interesting yet unfortunately many of these future entrepreneurs will fail.

Over 80% of new businesses fail in the first 5 years, and 96% fail within their first 10 years according to the U.S. Department of Commerce.

So, how do you hedge your bet?

According to Bill Gross, founder of Idealab, it’s not the idea, plan, business model, team, or surprisingly, even the money that’s the most significant factor in a startup’s success. It’s all in the timing.

Team closes in on ‘Holy Grail’ of room temperature quantum computing chips | PHYS.ORG

Huang and colleagues, including graduate student Jiayang Chen and senior research scientist Yong Meng Sua, dramatically boosted system efficiency by using a chip made from lithium niobate on insulator, a material that has a unique way of interacting with light. Unlike silicon, lithium niobate is difficult to chemically etch with common reactive gases. So, the Stevens’ team used an ion-milling tool, essentially a nanosandblaster, to etch a tiny racetrack about one-hundredth the width of a human hair.

Before defining the racetrack structure, the team needed to apply high-voltage electrical pulses to create carefully calibrated areas of alternating polarity, or periodic poling, that tailor the way photons move around the racetrack, increasing their probability of interacting with eachother.

Chen explained that to both etch the racetrack on the chip and tailor the way photons move around it, requires dozens of delicate nanofabrication steps, each requiring nanometer precision. “To the best of our knowledge, we’re among the first groups to master all of these nanofabrication steps to build this system—that’s the reason we could get this result first.”
