do you even time dilation?

all a light speed space traveler would need to traverse the entire universe is ~70 years.

-Nikola Tesla

Brooklyn Eagle July 10, 1932 Nikola Tesla states:

I have harnessed the cosmic rays and caused them to operate a motive device. Cosmic ray investigation is a subject that is very close to me. I was the first to discover these rays and I naturally feel toward them as I would toward my own flesh and blood. I have advanced a theory of the cosmic rays and at every step of my investigations I have found it completely justified. The attractive features of the cosmic rays is their constancy. They shower down on us throughout the whole 24 hours, and if a plant is developed to use their power it will not require devices for storing energy as would be necessary with devices using wind, tide or sunlight. All of my investigations seem to point to the conclusion that they are small particles, each carrying so small a charge that we are justified in calling them neutrons. They move with great velocity, exceeding that of light. More than 25 years ago I began my efforts to harness the cosmic rays and I can now state that I have succeeded in operating a motive device by means of them. I will tell you in the most general way, the cosmic ray ionizes the air, setting free many charges ions and electrons. These charges are captured in a condenser which is made to discharge through the circuit of the motor. I have hopes of building my motor on a large scale, but circumstances have not been favorable to carrying out my plan.

also tesla said:

"Einsteins relativity work is a magnificent mathematical garb which fascinates, dazzles and makes people blind to the underlying errors. The theory is like a beggar clothed in purple whom ignorant people take for a king... its exponents are brilliant men but they are metaphysicists rather than scientists."

Let the future tell the truth and evaluate each one according to his work and accomplishments. The present is theirs; the future, for which I really worked, is mine.

The two slit test?

im new to /sci/ so bear with me please.


i was playling fallout 3 and got an addon that got me a weapon called the Tesla cannon. i looked up its stats on the computer and one way or another came up with a source that said supposedly Nicola Tesla actually developed plans for one and that the design was the Tesla cannon in the game. naturally i wanted to find out if it was true and it seems like he tried getting the military to fund research for it but was denied and the military confiscated the plans for it.

all i know is if he had plans for it and wanted funds from the military he must have felt confident that it would succeed. i kept turning the idea in my head and i thought, wouldn't the two only problems be making the "shot" go where you wanted it to, and power?

i mean you need a HUGE Tesla coil to get a 5 foot bolt, don't you? it would have to be focused in some way?

Have a dilemma here /sci/..

I want to pursue Electrical Engineering. Problem is...in HS...I never went past Algebra 1. No...I'm not stupid..I was just lazy and didn't care to go past anything I didn't have it. I did what I had to pass and nothing more.

What resources are available to me so I can self teach myself what's required to enter an Engineering program?

Like the minimum level of math I need and such.

Any sites, forums, resources, suggestions would be greatly appreciated.
