The Chinese college application works way differently from American ones. The admission rate is meaningless. Zhejinag University is state assigned 985 university (there are in total 9 of them). Believe me any students in elite high schools

I think what the author want to convey is that the metric system was designed based on the assumption that pi^2 = g. The assumption pi^2 = g is one of the source of the metric system (at least for the relationship between meter and second).

In 2006, I had my first laptop right before the release of Windows Vista. Unfortunately, running Windows Vista makes my laptop hot and the fan kicked in to make a lot noise. I cannot remember the software's name which can reduce the co

Surface Pro 4 had broken OpenGL driver. Every software that requires OpenGL (basically all CAD software) crashes on it. Microsoft has all the incentive to cripple OpenGL. A generic Intel graphic driver cannot even be installed on surface. Y

Lenovo Thinkpad X12 is also a good option of "work" Tablet. A refresh is coming. Having been using it for SolidWorks, Altium, C development for a few years now.

this VNA is super great. for $600 you get up to 8Ghz (not a typo, 8GHz can be archived in harmonic mode) usable range. with two of them you can do 4port measurement. you can also produce time domain reflectometry with it. open source hardwa

For me it is lack of high end mechanical/electrical CAD software.

In a different perspective, the magnetic field itself is a result of special relativity. The magnetic field is an alternative way to explain electromagnetism without citing special relativity. (Or to say, electrostatic field and special rel

XRD used here only shows crystal lattice information for random orientated polycrystalline. It does not mean the two samples are identical. It does not prove whether they had single crystal or polycrystal. You will need a four-circle diffra

I am confused at the beginning, but it seems to me the author did not know the difference between diffractive optics and Fresnel lens. That significant reduce the credibility of the author. It is embarrassing for someone in academia to conf

Also don’t forget US domestic PCB vendor often have to go through quoting process. Which can add significant delay.

I you are located close to a DHL hub, then the order from China can come in 2 days, which make the international order a moot point as disadvantage. JLCPCB provide 24-hour run on 2-layer board.

the author should talk to an FPGA engineer about build/compile time. That will make any computer programming language look like lightning speed.

Magnet there is probably used as an isolator. The laser can only go out,but not come back.( yes, there will be laser coming back from reflection, which also interrupt the operation of the source laser.

Those are not prism. Prism implies it used as dispersion component, which is not the case. The thing does the real work there is the dichroic thin film coating on those prism shaped glass.

My personal opinion is that the eye development is an adaptive process. During the eye development, the body has a feedback system that make sure the eyeball size matches the lens focusing capability so that the eye can focus to infinity. H

Assuming the AI work perfectly, it will only be as good as the circuit simulation it can do. Unfortunately, there are some many things the start-of-art circuit simulation software cannot do. I really doubt the claim the author made here. Ba

This is to the point. The universe is a giant big computer even without quantum involved. If the starting state of the computation is not predefined, the so-called computer is no difference from randomly flipping some coins. What the paper

The picture in the original article is an exaggeration of the real condition. There are bunkers with much better condition than what the picture shows and still very cheap to live in. I have lived in those bunkers for short time about 15 ye

These bunkers has multiple rooms. It is not uncommon to have 8 people living in one room, and a large bunker site can have 20+ rooms. A bunker site can have living area similar to a 20 room motel, underneath a much bigger building on top (a
