How fast does a fly have to fly into a speeding locomotive to stop it?

Basic physics is so silly.

You get to higher level physics classes and its like "well everything that you've been doing up to this point is mostly wrong"

RIGHT?!

They fed us so many lies, lol.

"BTW, virtual particles can appear out of nowhere by borrowing energy from the universe, but they don't violate the energy conservation law as long as they give the borrowed energy back to the universe in a small enough amount of time."

As long as you don't have to go to the humanities building, weird thing happen around soc/history profs.

While I breathe, I hope
The result justifies the deed.
Between hope and fear
So the glory of this world passes away;

But Fortune favors the brave,
Fortune favors the bold,
thus you shall go to the stars.

per ardua ad astra,
through difficulties to the stars

Poem about my life sucking right now, lol.

Actually, it seems like a well thought out answer to feelings of depression or boredom with the tedious.

I just fly through here with blinders on, oblivious to the plights of others. I tend to miss a lot of stuff. Sorry to hear that, bro.

Mountain Muscle did bring up a good point in this thread. We should watch out for becoming like the Greeks. Physics did not evolve under Aristotle's tutelage because the Greeks were too caught up in thier own intelligence to experiment. They thought it to be menial and the work of slaves.

From a railroader, here are some things to consider....

1. Engine weight alone is 400,000 - 420,000 lbs. "Train" weight can be above 10,000 ton. "With their 4000-6000 hp per engine, even a car or truck does not slow them down, even if we are dragging them along. We could drag a car 100's of miles no problem."

2. There are two feul shut off buttons. One in the cab, one by the fuel tank. Each has to be held in for several seconds to be operated.

3. Trains are not aerodynamic, they will push air infront of them, therefore we get very little bug splatter on the windshiel. Unless the bug is very heavy.

4. IF, the emergency brake is applied and we are going fast enough, we WILL derail. That is why it takes so long to stop a train. If we hit a car and going 50+ , we DO NOT hit the emergency brake. It would be an even bigger mess and most likely kill more people. "Also, it isn't easy to accidentally put a train in emergency"

5. This is a silly ass question with only one answer, not possible.

Haven't really directly mentioned it publicly.

My advisor recommended a surgeon in the area here, and when I saw him, his first words were, "well, that doesn't look good." Ugh. He recommended another surgery right away, and my advisor agreed. My response was kinda "WTF, you're supposed to be on my side!"... I didn't actually say that, but, ... lol. I weighed the options for a couple weeks and decided to go along.

I feel pretty worthless being here not attending classes, so I've been on EF more, and I'm reading the stuff Matt posted, lol. Hence the poem.

Funny, you can replace Greeks with Americans, Aristotle with any prominant PhD doing research in the field, and slaves with grad students, and it bares a striking resemblence to today.
