If you have ever looked at an old transmission electron microscope with a viewing screen, you know electrons are green ; )

True, but the comparison with old technology makes the video more interesting. The replacement for the hydraulic actuators and also the twin scanning system are motivated by the hi…

Replying to your first point. There is actually a new branch of science called extreme event attribution [1]. Basically all weather events are now analysed to see how much more pro…

Modern nanotechnology is a multi disciplinary approach using effects on the nanoscale for new technologies. Therefore people from different fields come together to synthesis, simul…

The connection is pretty stable and worked great during Homeoffice.

12gb on mobil. Landline is without a cap, but I heard if you consistently download 5-10Tbs per Month, customer service might call and ask if you want a „better“ contract ; )

Those were the measured speed +-3 Mbps. Sometimes inside of buildings my connection also drops back down to edge but I think this got way better in the last 2-3 years.

Mobil: 360 down/50 up ~40€ Landline: 250 down/50 up ~50€ For the landline we also have the option of 1Gbps, but I dont want to pay for it.

Do you use a digital labbook? If so what do you use? I am currently trying MS OneNote. Just pasting everything in. Pictures, screengrabs, thoughts parameters. But I am wondering if…

I had some fun with this. After a while you can find a lot of clues to spot the ai picture. I looked at ca. 15 pictures and got two wrong. Then this happened: https://pasteboard.co…

This is the problem with historic games. Either you acknowledge the bad and good things, or you white wash the past. As the author notes at the end: „As I have argued here many tim…

Maybe thinking about lightspeed as the upper speed limit helps? You could also think about the clock experiment by Hafele and Keating where two synchronised clocks where flown all …

Wow! I was asked by a friend if dead/flat batteries were weighing less, since I was working a little bit with batteries. Back then I dismissed it as utter nonsense. But I still goo…

Very difficult to read. Some anecdotes were interesting but other than that I am not sure what my takeaway from this article is.

I was also confused. I thought this article was about how the cold fusion hobbyist movement is dying down because the topic is becoming unpopular. Fusion and cold fusion are discus…

Saw this video explaining in a HN comment why stronger magnets and a different approach might make fusion work. After ca. 22:00 Minutes he is done with the fusion basics and explai…

From which book is this?

Saw this on HN a while back. It also uses the socratic method to teach electronics, but student are supposed to look up the answers to these questions to deepen their understanding…

Yes the effects were great. Especially the city, but come on how could the story in the movie be sooo weak! Instead of an kickass army verteran we got Scarlett Johannson playing a …

I was pretty sure there was a seperate study where they debunct it? Gonna look for the link...

Worked for me on iOS 10.

Has anyone more information on the german secret court referenced in the article? As a german this is my first time hearing about that.

Unfortunatley not. The season ending was very disappointing.

Works for me after copying and pasting 17281580835365214242 it shows: 1,72815808353652E19

I feel sick reading stories like this. Yesterday I read about the guy that made a stupid facebook comment and is now facing 10 years in prison. He will probably win and walk away a…
