Thanks! Also, I made at least one bad typo. SQUID = Superconducting Quantum Interference Device... not inference.

I worked on a team (at a Company) that built a Scanning SQUID Microscope (SSM) to image magnetic flux trapping in superconducting circuits. The organization that bought the SSM is working on these kinds superconducting microprocessors. A

This is interesting progress but the key is actual computational benchmark performance such as quantum volume. It is cool to achieve 99.9 2q fidelity... this is vitally important. And high coherence time is also important. But you have to

The simulator didn't really mirror my experience but I do think folks should think twice about going to grad school. Economically, it is often not the best decision... plus you spend the best years of your life with less personal freed

So they are giving Musk ~8% of their current market cap. I guess the logic from shareholders is "if we don't approve the package, the stock is likely to drop more than 10%". I don't know exactly how the vote was carried

Great points... as to #3, investors are often happy to be buyers. They are buying shares anyways that would otherwise have to be created. Allowing founders and employees to sell shares lowers dilution vs. creation of new shares... usually

In my experience, and that of others I know, agreements of this kind are generally used to hide/cover-up all kinds of malfeasance. I think that agreements of this kind are highly unethical and should be illegal. Many year ago I signed

I can't read the full article but low-T MRI is potentially a big deal IMO because a 0.05T magnetic coil can be air or water-cooled but higher T-magnets (like 1.5 and 3T MRI magnets) have to use superconducting wire and thus must be coo

Numba and Cython can speed up Python code dramatically. Also, Python takes advantage of a lot of libraries which are C/C++/Rust at the their core. In many cases, it is possible to get Python code to within 2-10x of C using numpy&#

You may eventually run into trademark issues with PTC Creo, which is a CAD program. https://trademarks.justia.com/851/62/creo-85162134.html

Simply want to say thank you and you're awesome. I'm looking forward to the physics lessons.

MathCad works this way also, IIRC.

I've said this before... we need a open-source "(Git)Hub for Science" where anyone is allowed and encouraged to publish and continuously iterate on their 'research' and peer review is crowd-sourced from the communit

The board should say 'no' and counter with stock options. Overall,Tesla would be much better off using that 12% stake to lure and retain engineering talent. Musk starting work on AI at Tesla (which is already the case) and then in

US startup I work for is also shut down this week and has a very liberal unlimited PTO policy. I took about 6 weeks of PTO this year, for a variety of reasons, and no one asked a question about it. A lot of folks in the office work 35 hour

Burning plastic (and all kinds of other trash) for energy, if done well, IS economical/profitable and not much more 'dirty' than burning natural gas. I think a lot of refuse to energy plants in the US have been shutdown by en

I have looked through Prince's book (the free PDF) and think it is reasonably modern and pretty good. I'll probably pick up a copy at some point. I have the new d2l book. At ~25 USD it is hard not to recommend it... the paperback

Springer does sales all the time. I got the 3rd edition of Peter Corke's robotics book for 17 USD directly from springer earlier this year. I also got Nathan Ida's book on Electromagnetic, hardcover, for ~40 USD direct from sprin

And FWIW... 24V is very common for DC circuits in industrial control systems. 48V is used too but less common; however, 48V is very common in telecom.

Lets remember that most sedan [and smaller] cars do not fair well in collisions with pick-up trucks like the Ford F250... and neither do pedestrians and cyclists. Then consider all of the even larger, heavily industrial vehicles on the roa

Yep... I programmed PLC's for periods of my career. I could write about this until my fingers fall off, but in short: Rust and C code can also operate in strict real-time embedded environments provided some basic rules are followed li

I agree with everything you said... but there are a lot of areas in control system engineering that would benefit from having really robust hardware designs coupled with guaranteed correctness that Rust/Ada provide, and then all of the
