I would love to buy one, but I'm kind of broke right now. All I can afford are the parts to make one. Besides, I know they are very simple and effective, because I remember making some in Chemistry class in high school that consistently removed chemicals and other materials from water.
I am an 18 year old from Minneapolis and I plan on heading to New Olreans very shortly to help out down there. I am brining a van full of supplies and one of the items I would like to bring with is a water purifier and filtration system. I'm thinking the best set up I could have would be...
I have to write a brief history of physics for this english paper I'm doing. The only part I don't have a strong knowledge of is relativity, so if anyone would like to check the following three paragraphs for me and tell me if I summed it up accurately, I would be very grateful.
"Einstein...
What Fritjof Capra, in the Tao of Physics, said when he stated that what we call fundamental particles are "temporal manifestations of energy", he was saying that the entire universe is made out of energy, and this energy comes together to form what we know as quarks, leptons, photons, gluons...
Hmm... I'm still having trouble understanding this.
Let's say the box is 372,000 miles long (twice the distance light propages in one second), and instead of a bulb on both ends that I can activate, I have two men with indentical clocks who are instructed to both turn on a light when the...
So, Paallikko, let's say my box is at rest in space. I turn the lights on and I see the rays hit me at the same time. Then I accelerate to a speed that is near C. Once I reach that speed and I hit the lights again, how could they possibly hit me at the same time?
If C is constant, regardles...
Okay, thanks ellipse, that makes sense, I understand now. I still have another question, though.
So if I, with my lightbulb, am traveling at 50% of C away from you, Newtonian physics would say that C would appear to be 50% slower, but Einstein tells us that C would still appear to be at...
Confusion on just what "fundamental" means
I just read the Tao of Physics and I'm slightly confused. Are quarks and leptons fundamental units of matter or are they temporal manifestations of energy with E=mc^2? Is is that all matter is comprised of bundles of energy and that quarks and...
I'm just starting to learn about relativty, and I'm having trouble understanding it. Maybe someone could help? The first thing that I'm have trouble grasping is why would measurements of time/distance be dependent on an object's velocity relative to the speed of light?
