What's the inverse of
[eqn]y=2^{2x}\cdot5^{2x+2}-10^{x+1}+1[/eqn]
?
>pic unrelated
>>8148747
1/y=(1/22x⋅52x+2−10x+1+1)
You're welcome.
>>8148756
By inverse I mean the inverse function, like turning [math]y=2x+3[/math] into [math]x=\frac{y-3}{2}[/math]
>>8148747
x = log10((sqrt(y)+1)/5)
where log10 is the base 10 log.
Hello /sci/, I'm a dummy and don't belong on this board but I think I just came up with a genius idea, what if the justice system were run by computer programs? My reasoning is that computers can't be bought or biased, mandatory and harsh sentences could be scaled I think. Good or bad idea? Has this been thought of before? I was even thinking of trying to writing a shitty story about it (don't steal if you think it would be a good one)
>>8148740
You do not need a good program, just one that is better than the current system. Turns out computer are bad at making evaluations regarding people behaviour, so I will take a while, maybe forever, to make a good judge computer
>>8148740
>genius idea
>using computer for everything
Yeah, truly breaking news.
>>8148752
I only said that in contrast with calling myself a dummy anon
honestly I just wanted to see if you'd all debate the idea of it's coherent flaws and pluses
please weigh in
Found this cicada almost totally dead (it's legs were just barely moving) and it had these weird growths coming out of it. At first I thought that it was partially crushed and that they were some of it's guts but after picking it up I found that wasn't the case. Is it a parasite? That weird zombie fungus?

>There are people crazy enough to touch bugs
Absolutely disgusting. I have never voluntarily touched a bug because bugs are horrible.
Not exactly sure OP. You should try researching on what it is that you are speaking of.

I was wondering what the most optimal chemical competition for a bomb would be?

Somebody explain this. I swear it does the trick better than any medication. Is it just a placebo effect?

Simply standing up takes care of a lot of aliments.

Sounds placebo
If not go to a doc

Explain your symptoms more. I have a BS in PhD MD

Say you released a golden retriever puppy into a pack of wolves. Would the puppy be able to integrate into the pack or had humanity too thoroughly genetically cucked the golden retrievers ability to survive in the wild?
Domesticated dogs knew which animal was the greatest predator to follow. Wolves got cucked by nature and their shit judgment.
>>8148492
Coyotes wind up raising stray pup dogs quite often, and occasionally the dog will even make alpha status. (A bit less common among wolves, obviously.)
Even when you get to the point where physical genetic alterations put them beyond all usefulness (Chihuahuas or what not) they seem to adapt fine. They don't become alphas, obviously, but the pack will still raise and defend them, at least some of the time.
Once in a great while, canines will even raise humans.

It could die of plain disease, parasites, cold, etc. Sometimes omega wolves are expelled from packs, become giant lone wolves otherwise they starve, and then make their own packs.. Epigenetics would play a big role here. The puppy could survive if females liked him and if the pack wasn't starving.

Great video.
Dear Anon, sorry for creating this stupid thread but I am in need of your help I want to study something technical but I don't really know what the smartest choice would be I really wanted to study economic computer science but I am afraid, that it will be worthless and I won't earn a lot of money, which to be honest is one of my goals later in life, I only know that I definitely want to study something technical, what would be the smartest choice?

you should learn math and programming perfectly.

We can prove that for any finite group of order n, it must be true that the order of any of its elements divides n. However, does there always have to be an element of order d for all divisors d of n?
I tried proving this in general and for Abelian groups, but couldn't quite get there.
>>8148416
Obviously not you cretin, that'd imply all groups are cyclic.
>>8148416
the strongest result in this sense is Cauchy theorem
The group [math] (\mathbb{Z}_2)^3 [\math] is an abelian group of order 8 with no elements of order higher than 2.
I don't understand.. how can the SPHERE be the SHADOW?
Like a rainbow man. The sphere is a shadow of particles. The thing just has the necessary ability to make its shadow curved and spherical due to the nature of how the particles reflec light.
You have to remember that AT fields exist there so there could be any number of surfaces for light to bounce off and form a sphere

Why haven't we solved turbulence yet?
>>8148206
Because it might not have closed form solutions.
Turbulence is caused by wind, which is caused by tempurature changes in the weather, or by Induced Drag. All you can do to treat it is by being a good pilot and maneuvering through or around it.
Induced Drag is a natural byproduct from generating lift, and your pic related is whats called Wing Tip Vortexes. Theres minor things you can impliment onto the wing tips to help stop those WTVs but i think it is just natural. I'm interested in figuring out how to utilize WTVs for the plane.
One idea i have is setting up spinners that catch the air current and spin...

Preparing for a Japanese Scholarship exam, it consists of Chemistry, Physics, Math, English and Japanese.
My biggest fears are the scientific parts, Chemistry, Physics and Math, I love science but I am a student who just graduated High-School from a 3rd world curriculum which is based on memorization and vomiting out all the memorized info on a test paper at the end of the school-year. Because of this, and Shit teachers, I have shit foundations in science generally as well as math, but I love reading about science and the application of it. What do I do to prepare for...

just go to college in your own country.
its not worth going to a foreign country where you already admit you have a poor understanding of the concepts.
>>8149176
Don't listen to this guy, OP.
If you want to do it, go for it. There's material free and accessible on everything if you go by a curriculum and look up each theory individually.
>>8148134
It's very difficult taking exam in format you're not used to... especially when you were scoring high on the format you were very used to. I experienced this when I had to quit A level program for america. Knowing what question wants is crucial
Nothing's bad about memorization. How do you even do that in physics? It's all about understanding concepts in physics anyway. Well good luck
/sci/ I'm moving into and starting college this sunday. I'm going into a physics major and possible a double major in mathematics. For those of your majoring in them right now or have graduated, is there any advice you can give me? I mean specifically for physics and mathematics that is. I have torrented textbooks and all sorts of shit on a drive which I'm going to study with in my free time, will I even have the time or will to do this? I still want to have time for hobbies though and parties. I'm a pretty smart guy but regardless, anyone is going to have...

I have. I'm asking everyone personally. This is why I don't come on this board much, every single time I start a thread, no matter what's it about, I get this response.
I'm from england, but I just finished my first year studying pure physics. If american universities are anything like ours, your first year will be piss easy.
So help me sort this out
Why are we still sticking to the science meme?
Who cares about the arbitrary and tedious scientific method?
Why are we wasting time with observations and guesswork when we should instead only focus on what we can rigorously derive using pure logic and pure mathematics?
Maybe it's just my math background talking, but who cares about experimentation? It doesn't prove anything. The next experiment can have results that completely invalidate all the previous ones. Why waste time and money on that instead of proving things for real?
It's...
