Anyways, this scientist claims that if you detonate a megabomb underwater near a coast, you could create 1200 meter tsunamis that would flood the land near it.
Is he right?

I figure this board is mostly STEM majors, so I'm curious to hear how many of you are working while going to school (regardless of its relevance to your field) and how you balance it with your workload.

I cranked out school and then work hard during the summer to pay for the school.
Jobs during the school year is difficult - I used to have a rule where I wouldn't work over X hours a week where X is the amount of credits I'm taking for the semester. Half that amount during exam time. Good luck.

Sooo what would a second of life occupy in terms of bytes?. Besides the "video recording " other senses should be also taken into consideration.
At 60fps the human eye can record about 250gb /s. But also , how much does an emotion occupy?

Emotion is merely a type of lens.

What do you think of the idea behind Bitcoin?

Bitcoin was created by some entity who claimed they were libertarians and wanted an alternative currency not controlled by the FED.

What do you think of this idea?

I understand that the FED controlling currency might mean they are indirectly messing with your true net worth.

I understand that the FED controlling currency means that they are choosing winners and losers because some people benefit and others don't.

But it seems to me that a nation that can effectively control their currency is ultimately superior to one that doesn't.

What do you guys think? Is there any merit to this hype against the FED?

Central banks exist only to enrich the already ultrarich.

>But it seems to me that a nation that can effectively control their currency is ultimately superior to one that doesn't.

The Federal Reserve is a PRIVATE entity which is not part of the government nor is it accountable to the public. So who is in control really? Would you rather it be them or that the power be decentralized?

I like the concept of Blockchain and currency mining.

it's a way to generate currency while in the same time generating more security by solving hashes (if I understand correctly)

the problem with Bitcoin is that it's bound to real currency and can be used to buy and sell other currencies. This fact nullifies all the neat advantages of digital cryptocurrency (cc) and makes it just another electronic payment method.

Things that are missing:

• global acception and participation on cc
• currency trading using cc should be prohibited
• either all legislators should be obligated to save the blockchain continuously
• mining plants need to be regulated more or should affect gain to avoid centralization

that's the problems I can think of the top of my hat.

If you are seriously that stupid to think it was created by literally nobody they are dead wrong.
It was experiment for the future to see how much is needed for people to transfer their believe in the monetary system that is based on non material objects.
American monetary system is already based on something that is not Gold,its called thin air in most places.
It only showed that is vulnerable as any currency through history therefore useless.

How would one scientifically prove that there's no current flowing through this circuit?

I got into an argument with "that guy" who thinks that the universe doesn't exist when you're not looking at it. He also thinks it's plausible that a small amount of current could flow through this circuit, but attempting to measure how much would involve breaking the circuit and at the moment all the current would magically vanish.

the answer is litterally magnets
>>
>>8833981
actually, throw a magnet through the loop and current will flow in it as long as the magnet is moving

you could measure it without breaking the circuit by using a clamp on ammeter

back to normiebook now please
>>
>>8833982
wouldn't magnets slow down or at least apply a force on the current?

Physics is more rigorous and definitely requires a higher IQ than chemistry. Chemistry may be a little harder in a lot of decent schools just because of the sheer tedium and bullshitting involved.

Read calculus books. As a first one I recommend Stweart but the board meme is T. Apostol.
>what comes after that?
In that branch of mathematics? Analysis. But there also is algebra, geometry/topology.
