how do i know if i am feeling an emotion

I'm seriously considering enrolling into university for Mechanical Engineering (not underage). But I have on problem, I'm semi decent at calculus (mid 90s) but my chemistry and physics mark are at high 80s to low 90s.

Am I in good shape for engineering or no?
Also how is the eng. life in general?

I was going to ask question relating to this subject in another thread. So let's say there is a fusion powered generation ship. Now in this generation ship there is little car sized space ships, what sort of fuel would these things use.

Does anyone else believe that CERN has already found a way to create micro black holes and just never divulged this information?

has there ever been any real scientific research about penis enlarges? Is it true that strething your penis will cause mitosis to happen and create new cells making your D bigger?

I am in Physics 20, missed a class and im fucked. We have a graph of Velocity vs Time, and we have to solve distance using slope and area formula not kkinematics formula. I looked online googled this formula and it is always
y2-y2
x2-x1

Which just gives me slope, how the fuck do i solve for distance by not just going Velocity times Time?

I was in a rut and I'm old and want a career before I finally hit 30

Will I realistically hit 50k as a salary faorly early in my career?

I don't expect huge amount of money, just enough to consider a family.

Alright guys, I'm arguing with my dad about how solar power generation works and need some clarification.

Essentially I need to know how selling power back to grid works.

Pretty much I need to know how the wiring/electricity moves/works.

When electricity is captures to sell back to the grid, does it go through separate wires, or the incoming ones?

I just need clarification about how selling back to the grid works from residential panels. How does the electricity actually go back to the grid?

I came up with this today.

You could say a theory is x% representative, which you get by dividing the number of cases where it works by the number of all possible cases.

For example, take a function F(a,b) which behaves as a logical OR. The theory that it behaves as a logical AND is then 50% representative: it works for (0,0) and (1,1) (2 cases) and fails for everything else (there being a total of 4 possible cases).

Is there any website where I could translate specific Biological phrases/termins from English to my language?

Are there any function with one variable that has two y values when graphed?

What is the lagrangian of a system moving as the result of solely conservative internal and external forces?

I'm not quite understanding what's the V or "potential energy" component of the lagrangian if I have external forces with potential U and internal (interactive) forces between particles of the system. U_ij is the potential of the interaction force between the i-th and j-th particle.

Is it just L = T - U - U_ij?

Was thinking about testing the effect fertilizers have on enzyme activity, sound simple enough to do?

Why do people say "don't waste water! you will be sorry when you have none" I can see doing this if there is not a lot around.

But if you have a almost unlimited amount what's the big deal? Could the world actually run out of water? This just seems like nonsense as it has to exist as either a solid, liquid or gas. Where would it go? Space? wouldn't it just get pulled back in via gravity?

Linear Algebra question /sci/

The topics involve least squares solution of Ax = b

If we suppose S is the set of solutions of the equation Ax =b, and L is the set of its least squares solutions, how would one go about proving S is a subset of L?

Don't' let them(U.S. Military, Israeli IDF, U.S. Secret Service, NSA, CIA, DHS, PLA, etc..) install such neural programs on the masses of society.

Can someone explain to me the difference between impulse and work? I know that impulse is F * t and that work is F * s, but what's the difference in their concepts? aren't they both just energy transfers?

any ideas?

Quick physics question /sci/.

Imagine a motorcycle traveling over the top of a circular hill. At the very top point of the hill (being vertical to the center), wouldn't the centripetal force be the force of gravity? Meaning m*v^2 / r = m*g ?
