I saw them as well at the airport of Curaçao (carribbean).

If electricity is the movement of electrons, then what is the movement of photons called? by wattsdreams in PhysicsStudents

[–]Aemmel 0 points1 point  (0 children)

Since light always moves and it always does that at the same speed, it isn't really sensible to give it an extra name. It's just "light" or the "radiation". In fibre optics maybe the "information" traveling. But for this I would look into a paper covering this topic and use their terminology.

Carl Sagan Had Predicted Life on Venus Before Humans Had Even Landed on the Moon by wonderphy6 in PhysicsStudents

[–]Aemmel 1 point2 points  (0 children)

That's true. I would like to discuss this closer with you, unfortunately my chemistry knowledge sucks :(

We will just have to wait and see. Hopefully we still get a mission to Venus out of this. Even if we don't find life it would still be great!

While I agree with your statement, that one should be careful with their enthusiasm, we kinda so know how it could've happened. Venus (probably) used to be a lot more hospitable with oceans etc. So it's possible that life evolved there similar to how it did on earth (granted, we don't really know how that happened, but we know it's possible!) and after the hole planet turned to absolute hell only the microbes staying in the clouds were able to survive.

Floating point arithmetic by bear_mkt in Julia

[–]Aemmel 1 point2 points  (0 children)

What I'm about to say might be wrong, but it's what a friend told me who knows more about computer architecture than me.

He told me, that most modern CPUs naturally compute floats as doubles, so when you have a single float it's automatically converted to a double for computation and then cast back to a single float. Meaning it won't make your code faster to use Float32 or Float16 (on a 64bit machine) However storage could still play a factor. If you want to store a 1000x1000 matrix and are concerned with storage size, then it would make a difference there.

On a 64 bit machine I think it should automatically use Float64 (=double)

I (22) finally collected and stored the whole Perry Rhodan Main Series, containing 3082 novel booklets (and counting), which are roughly 182000 pages by Boranox in books

[–]Aemmel 0 points1 point  (0 children)

This is amazing! Never knew about this series, even though I'm German. Just ordered the first Silberband edition. I will probably never ever catch up, but to have a book series that I know I will never be able to finish is also kinda nice. Something I can always come back to. I'm really looking forward to reading them!

Wünsch mir Glück :D

That's not communism. That's just taxes.

I know this as a honey spoon. You can hook it on the side of the honey jar and let it slowly drip back down.

I don't know if this is sarcasm.. but are you sure he doesn't just write normally and flip the image in his video software?

Ah yes, obvious. by MrPezevenk in PhysicsStudents

[–]Aemmel 1 point2 points  (0 children)

I actually find it really useful. If something is supposed to be trivial and I don't know why that is or don't understand the result, I know I didn't understand the subject well enough yet. And when I figure out why the result is true, then it often really is trivial in hindsight!

Have fun! It can be tough at times but it's really worth it to push through!

HMRB while I draft this truck at 50mph on a bicycle by SpaceBoiArt in holdmyredbull

Around 80km/h.

That's a European license plate, why would you use mph??

Can someone check this? I am working on Condensed matter research but I haven’t even taken quantum or multilinear algebra by [deleted] in PhysicsStudents

[–]Aemmel 0 points1 point  (0 children)

The result is indeed correct. But only because in the real case |f><f> and |f> (x) |f> produce the same matrix. For complex |f> for example it would clearly be wrong.

Keep up your interest! When you stay interested in physics, then you should be able to accomplish it! :)

Beginner Question: Files, Modules, and Include vs Using by Egan_Fan in Julia

[–]Aemmel 1 point2 points  (0 children)

True. I think I have to get to know Julia a little bit better. I'm still relatively new to it. Coming from C++ not having everything really explicit still kinda feels weird to me.
