>Gravitational Waves
what would this discovery imply? that chikung type energy work is true? that you can manage discrete amounts of energy at distance? whats all the fuss about really?

it would confirm general relativity. groundbreaking for sure but it's not like we haven't already got a shitton of experimental tests for GR.

How can you even detect something like gravitational wave ? Sounds like bullshit

>tfw I read some faggot here claiming that the physical peak (mental and physical) of females is 25 years old while males is between (can't remember) 30-35 years old
can someone comfirm this?
I would like some good cientific citation or paper I can read and not dating advice BS.
The only thing I found was that females tend to find the most appealing males between 5-10 years older than her on average while males find the most appealing girls bewteeen 15-25 years old.
Does this mean a virgin beta that is 25 have enought time to change it's mentality and be an alpha chad at it's physical and mental peak to slay god tier pussy from legal lolis (we can fuck 14 years old legaly here in taco land) to MILFS, right?
I dunno, but I feel females tend to be impressed not because I'm hot (average brown manlet, not fat) but because I can usually talk with confidence about lot of stuff (basic pleb tier culture).

>rotating neutron star that emits a beam of electromagnetic radiation.
>neutron star
look up P-P chain and CNO cycle, the lifetime and form of a star depend on its mass.
Normally a star is prevented from compressing by its own gravity as long as the nuclear fission is going, the star is so boiled that gravity doesnt really compress the star itself, but if the fission runs long enough, such that it comes closer to iron which is stable. The star doesnt "boil" anymore and compress itself by its own gravity.
If it compress to the point where even electrons are pressed inside the nuclei, the proton and electron form neutron, meaning the whole star is neutron star.
I am no expert but i know black hole can have different size, i am not sure about such property for black hole but a neutron star doesnt necessarily have mass large enough for light to not escape.
As for radiation, both rotating black hole and neutron star emit radiation like pic related.

How to tackle humanity's issue about over-population:
1. Find a sharp utensil.
2. Calm yourself by stating "My intelligence transcends all humanity, desu!"
3. Find as many alive, male humans as you are capable.
4. Remove all their testicles.
5. Place testicles in mouth.
6. Try to say "I am Άλφα-stein!"
7. Pierce your windpipe with your sharp utensil.
Now, the problem is solved, all the thanks to you, dick head.

Define 'break'? As far as I am aware, the Oxford English Dictionary defines 'break' as: "To separate or cause to separate into pieces as a result of a blow, shock, or strain."

prove the scalar product of AC.DF=0
knowing that AB=a

AC = AD+DC
DF = DH+HG+GF
Then expand the dot product
>>
>>7785252
please continue in more detail.thx
>>
>>7785252
so it's possible to expand the dot product the same way as any algebric product ?
and the answer becomes;
AD.DH+AD.HG+AD.GF+DC.DH+DC.HG+DC.GF=0

What if dark energy is used as a cloaking mechanism to hide the presence advanced civilizations or starships?
Dark energy is like the perfect stealth field
>zero thermal emission
>zero EM presence
>zero reaction with anything other than perhaps gravity
>primitive humans can't even detect it directly

Hey /sci/ I have a 13 page exam I need to deliver in 2 weeks
My subject is radiography and ethics/communication
I need problem and some themes and a problem to write about
Any ideas? I basically need an ethical dilemma within communication or ethics in the field of radiography (x-ray, radiology, medicine)

What can even be unethical about radiography
>>
>>7785171
patient care, radiation protection
>>
This is more of a genuine question from a physicist than an example but it may work for you so here goes.
Why is it safer to perform radiography exams on a pregnant woman up to a certain point in the pregnancy rather than performing them after a certain point. An unborn fetus is always growing and the number of cells early on are nearly countable. If one of them is damaged it is a larger overall effect on the fetus, so why not have the idea that it is ok to perform these procedures after a certain time rather than the other way around?

Soon to be math/science teacher here. In about 5 months I'll have finished up my degree and will be qualified to teach math, chem and bio all the way up to high school. However, I have some major anxiety. Despite having done these classes myself while in high school and having done plenty of university level units, I'm terrified as to how I'll remember everything I need to know. I glanced through a past final exam paper for chemistry and already found so many questions I'm stumped on.
I've already taught in schools as a student teacher but they were all grades 7-10 which is all really straight forward. I still have one more run as a student teacher and if I don't get a chance to teach a senior class I feel I'll be screwed having to teach one for the first time on my own when I graduate.
Any other teacher here? How do you cope with keeping on top of remembering your content? How much time do you spend retraining yourself?

Get a camera and film yourself teaching in front of a whiteboard. Just imagine a class.

You know how students study for exams? Well, teachers study to improve their classes.
Just calm down a bit. It's not about having everything in your memory, but to be able to understand and teach the concepts. Plan your classes ahead, make helpful presentations, check the answers to your exams with software, and enjoy being a teacher.
ACTUALLY, that's the most important part. Enjoy to be a teacher, otherwise, don't even bother to ruin other students' dreams.
>>
>>7785077
If someone asks you a question that you've forgotten the answer to, teach them how to find the answer.
You cover your ass, and good research skills are probably going to be way more important for most kids than high school chem. anyway.
