Maxwell's Color Science - AAPT Winter 2021
Просмотров 7403 года назад
All physicists know of Maxwell’s equations. Many know of Maxwell’s statistics. But only a few know of Maxwell’s color science. In this talk I will discuss James Clerk Maxwell’s work on demonstrating trichromatic vision, including his experiments with the color wheel and color box, his empirical color triangle and the first ever color photograph. Further, I will highlight two ways that you can t...

The Influence of Christianity on 19th-Century Physicists
Просмотров 514 года назад
I gave this talk at AAPT Summer Virtual Meeting 2020 as part of the session on Religion and Science. The 19th-Century was a period of giant leaps in physics. Young demonstrated the wave nature of light. Dalton developed atomic theory. Maxwell unified electricity and magnetism. The list goes on. At the end of the century, Albert Michelson famously declared, “There is nothing new to be discovered...

The Nuclear Bombing of Hiroshima and Nagasaki
"Force does not exist physically in the same way that an object with mass does. This means that force cannot make surface contact with an object, much less push or pull it. The initial cause of all bodies in motion originates from the applied energy (E), which creates the momentum (p) necessary to make surface contact with an object, thereby enabling it to push and pull. This concept is mathematically expressed as Ep or the equation Ep = ma. Force was originally used as a placeholder by Sir Isaac Newton because he did not know the true nature of this Force." ~Professor Guadalupe Guerra from Laredo, Texas c/s
Thanks so much for this! I'm not very familiar with SparkVue and I've been trying to figure out how to do this efficiently with only one pair of carts but an entire class of students... it hadn't occurred to me to set it up with different pages and different runs (so each individual/ group can collect data quickly then move away to analyse it all later). Cheers!
hello ma'am, may i know if where did you get the tools you used and what are those? especially that motion sensor, if I'm not mistaken.
Good experiment but you should have displayed the table of results.
hi what software you're using for Velocity? thanks
It's Pasco SparkVue software (made by same company that makes the smart carts)
Circle is 1 dimensional or 2
Good keep going
This is so thoroughly explained thank you I'm doing my practical tomorrow
Provided that we know the distance the weights travel as well as the time it took. We can calculate the acceleration and thus calculate the earth's gravity.
Love it!
Another clear explanation! Thank you!
Great video.
Love the way you teach
F=ma thats why hammers have big heads
Bare & instructive enough with realistic measurements. Thanks for your exertions, Dr. Macko
well explained Sir/ ma'am.projectile motion class 11 ruclips.net/video/0tq4fO16NLE/видео.html
Nice
Thank you, professor, for spreading knowledge. We appreciate this
Great expectations ✌️
Well explained, thanks
Great job
thx a lot
Ma'am what is the use of this experiment 🤔
The purpose of this experiment is to determine the mathematical relationship between the acceleration of an Atwood’s machine, the difference between its two masses, and the sum of those two masses. It's good practice of Newton's Second Law, the particular forces of weight and tension, and the geometry of pulleys.
Not a good job at demonstrating what the thing is designed to do.
You are erong.
Thanks very much ma
what is the hypothesis
Net force is directly proportional to acceleration
This experiment demonstrates Newton's Second Law: F = ma In words: the acceleration of an object in a particular direction can be calculated by dividing the net force acting upon the object in that same particular direction by the object's mass.
Does it also explain the effect of acceleration when mass increased
thank you for the video
Thanks for the video!
Mam nice explation
