ICH LIEBE PHYSIK.

Hello, in November you mused about technology being magic and rhetorically asked how wireless charging works. Since it was a rhetorical question you can completely ignore this message entirely, but otherwise I'm gonna give the short version:

Electricity happens when you cause free electrons to move in a conductive material, right? A battery pushes these free electrons in one direction. The electricity in modern homes is AC, meaning alternating current, meaning when you plug something into the wall the electrons don't just flow down electrical wire in one direction like a battery does: they switch directions 50 to 60 times a second (depending on what country you live in).

There's a wire wrapped in a flat coil both inside the charger and in your phone. When electrons move back and forth through a coil, like when you plug your wireless charger into the wall of an AC outlet, the electrons moving back and forth create an alternating electromagnetic field. When you place your phone on the charger, the force of this alternating electromagnetic field pushes and pulls the electrons in the coil in your phone, which in turn makes electricity in that coil to charge your phone with.

What's funny is this isn't a new concept at all; the electric company sends hundreds of amps and hundreds of thousands of volts (big electricity¹) through the powerlines outside. They go to a transformer that is turned into the tens of amps and hundreds of volts (small electricity¹) that your home uses. In order to transform the electricity, a big coil and a small coil sit between a barrier inside the transformer. The big electricity creates an alternating electromagnetic field and "wirelessly" pushes and pulls the free electrons through the smaller coil (in the same way your phone is wirelessly charged) to make small electricity for your home to use. So we've technically always had wireless charging :)

Anonymous asked: as an addendum to my previous anon: it is still no less than magic. Thank you.

hey dude do you know what else is magic? the fact I think I understand wireless charging now. thank you very much

Do y'all think that Glorfindel ever slipped up with Elrond and Eärendil, like, after babysitter Eärendil like forever, him having a son would have been so weird. Maybe he told Elrond to finish his vegetables and Elrond is like dude, this is my daughters wedding.

The long awaited (for me) mha oc art! Here's a visual timeline of them throughout the years :). The guy on the left is Adam, and the chick on the right is Avery. They are siblings :))

bin grad am versuchen physik zu lernen... da gehts um den elektromotor und ein teil davon heisst stator und ich les die ganze zeit nur spatort😭

spatort living in my head rent free, sag ich da nur, aber ist auch gut so

[asubax]

manchmal würd ich gern irgendwas naturwissenschaftliches studieren - einfach, weil die viel geilere räumlichkeiten haben lol

Plays

Round 1

The Physicists :

This play is a hilarious satirical comedy. From the Wikipedia entry: "The play deals with questions of scientific ethics and humanity's general ability to manage its intellectual responsibility. It is often recognized as his most impressive yet most easily understood work." I have read it in both English and German and it is really clever.

so, im rereading the septimus heap books and maxie was a wolfhound puppy when jenna and septimus were babies. i always thought he lived a very short life, but now i realize, it was tragically short like i had originally thought.

Why Is The Nuclear Fusion Theory Wrong?

(1)

Where's Planet Motion Energy?

Any moving body produces motion energy (1/2mv^2), but where's the planet motion energy? The planet can't store its motion energy inside its body because it would raise its temperature, and no planet temperature is raised by its motion- so- again (Where's The Planet Motion Energy?)

Logically, Planet motion energy must be stored in the space in waves form-

The space is similar to the sea of water and planet motion in space is similar to a fish swimming in water- the fish motion creates waves in water and the planet motion energy creates waves in the space- means- Planet motion energy is stored in the space in waves form. 

Let's see this picture accurately- we observe one swimming fish in the sea- the fish hits the sea water by its tail and pushes some water and by that the fish swims and moves- we conclude the water moves by a velocity Equal the fish velocity because of the reaction force- means- the fish swimming creates wave in the water and this wave moves by the fish motion velocity-  

Similar to that-

Mercury motion energy creates wave in the space- this wave velocity equals Mercury velocity (47.4 km/s) -means– while Mercury moves, its motion creates waves move by the velocity (47.4 km/s)- 

Shortly- All planets motions energies create waves in the space and these waves move by these planets velocities- The space waves are similar to the water waves, they move far from their sources and can be reflected-

The Conclusion

The planets motions energies are stored in waves in the space

And

I claim the gravitational waves are these space waves, they are produced by the planets motions energies and NOT by the Sun gravitational field 

(2)

Now we can answer our question (Why Is The Nuclear Fusion Theory Is Wrong?)

Where

the solar system is rich in the motion energy- the planets move and produce motions energies continuously and this energy is stored in the space – that tells – there's massive motion energy stored in the space- the logical idea tells this energy should be used to produce the sun rays- BUT – the scientists created very artificial reason for the sun rays production (the sun nuclear fusion theory)- the theory is wrong in principle because the theory left the stored motion energy without using in the space and created the artificial idea (which doesn't depend on any cycle or motion), while everything in the solar system depends on motions and cycles.

Thanks a lot – please read

Thinking abt the time when i was reading physik and i would quickly read through all the chapters that didn't contain marcia in search of another chapter that contained marcia

This semester brought to you by the letter

✨ K ✨

between chemistry and physics, this week there are five K's I need to keep track of. Two are lowercase and three are uppercase, but that might make it worse because the difference is often hard to tell with a handwritten k.
