It is not really just a kettle. Has integrated tea strainer, you can use it as a teapot. It is missing a proper tea cosy, however.

Major confusion for me, as SPICE is well known circuit simulator: https://en.wikipedia.org/wiki/SPICE Using it often. Mostly via ngspice nowadays: https://en.wikipedia.org/wiki/Ngspice

Has been done for decades. Buried capacitance materials like FaradFlex MC12TM exist and are really good, but are not too often used.

The (more common) package has very precise solder bumps. You can have a special order for one with ENIG finish as well, but this only makes sense if you have a really good use case (using Pb solder, wirebonding directly). Not sure what meth

Length of this capacitor is close to half-wavelength of 220 GHz (in vacuum). Using siblings of this broadband capacitor (40 GHz, same package) in some designs. In assembly, those require decent process control. This 0201M package is closer

2/156 lost for Soyuz in 59 years, 2/135 for Space Shuttle in 30 years. Same rate. People often underestimate how intense STS actually was.

In QC, keeping cold is not just needed to superconduct, but to reduce thermal noise to level below the energy levels operated at.

I am using Leo Bodnar’s fast pulse generator (SMA) in my lectures to teach transmission lines. With sufficient length (I use ~1m) it works quite well to demo with a low cost scope. I originally bought it for TDR with 40GSPS/15GHz scope

A similar concept has been used for university lectures to start 15 minutes after the full hour. This was due to nobody having watches and everything being synced to the church bells ringing at the full hour. Then you had 15 minutes to get

In my EU country Gardasil 9 is the most common HPV vaccine nowadays. This protects against 9 most common strains. I would assume the same is true in other countries. We have gone from HPV 16/18 -> +6/11 -> +31/33/4

If the input to the weather forecast is mostly /dev/random, then yes, that is called a lie. There is a very big difference between modelling chaotic systems and providing random noise.

Few things for starters: - you have to look at it in frequency domain as well; - speed of light is too slow; - often capacitors are inductors, even more so when mounted on PCB; - capacitance is not what is written on the component. I am tea

Funny thing is, that news, by definition, are written about things that are newsworthy. Newsworthy things are not common, but exceptional and rare. Thus one shall not worry too much about the news as those things practically never happen in

Used to develop readers based on similar UHF chips (868 MHz in EU). They were quite expensive compared to printed bar codes those were replacing. Also large. With (folded) antennas we are still talking about 40*10 mm minimum for the label.
