Not really, with current technology such a system would be astronomically expensive (~trillions of usd to build the laser). This paper is from 2021 which is right about when the breakthrough starshot program ended.

Kind of odd that they did not reference any of the existing work done by the breakthrough foundation/UCSB https://www.deepspace.ucsb.edu/projects/starshot In particular they have a few paper about lab demos of ph

If this holds to be true, this will absolutely be the key to this all. Absolutely incredible that she was able to get this paper out so quickly, and with such a critical insight to the problem at that! The paper also has this absolute gold

Just in case anyone else was confused, 'popcorn polymer' refers to a popcorn-like porous polymer that can form in petrochemical processing, not a polymer that forms during popcorn production. I was assuming it was something simila

I run a matrix server deployed using their annsible script [1] which comes with jitsi, etherpad, etc. The setup was a bit of a hassle (need to get the domain configured for federation, updating the config files etc) but after a weekend of c

Worth pointing out, the image in the article is actually of the 'Great Blue Hole' off the coast of Belize, which is about twice the diameter but half the depth[1] of the one in the paper. Also quite the opposite of 'recently

A true classic, I can't say that this is what got me into semiconductor physics but I also can't say that it was not what I based my understanding of semiconductor physics on for many years...

A very interesting read, which describes how for ~50 years the community was lead astray by a seemingly simple oversight: studying dead animals instead of living ones! >Charles Darwin theorized that monkeys had the vocal anatomy needed f

The link seems to be down, but from what I can gather this is linking to a forum post from 2021 where a user (possibly working on bricklink?) was asking for help. Presumably there was a more recent post since then, but I can't find it.

Clearly you should have compromised and hacksaw'ed out the usb jack + ftdi region of the board, thus satisfying both your desire to have something jankey and compact. You would even get free activity LEDs!

I love the electric part, infinite torque and practically infinite electrical power without concern of draining the 12v battery. It is basically a full sized generator which is always with you. On occasion I charge my other EVs from the onb

I am not sure what you are trying to say. My f150 pack did not explode (presumably what an 'incidence' would be in this case) but is still being recalled.

They are also recalling packs in the field, my truck is currently at the dealer getting a new pack.

This is absolutely not true, the speed of analog circuits is (by a significant margin) determined by parasitic capacitance, inductance, and resistance of the components. To put numbers to it, a typical high performance analog multiplier mi

Yes, I switched to XCP-ng in early 2017 and haven't looked back. While I am not super in love with Vates (and their incessant pushing of their saas products I have 0% chance of using) it is a great example of the GPL at work protecting
