WSU: Special Relativity with Brian Greene | 2020
WSU: Special Relativity with Brian Greene | 2020 Ambakisye-Okang Dukuzumurenyi 28 Views • 5 years ago

Physicist Brian Greene takes you on a visual, conceptual, and mathematical exploration of Einstein’s spectacular insights into space, time, and energy. In just 11.5 hours, using nothing more advanced than high school algebra, journey from Einstein’s earliest musings on the speed of light to his startling realization that time can tick at different rates to his revolutionary discovery of the world’s most famous formula, E = mc2.

This is a more in-depth and mathematical version of the WSU Master Class “Space, Time, and Einstein.”

Probability and Its Limits - Professor Raymond Flood | 2014
Probability and Its Limits - Professor Raymond Flood | 2014 Ambakisye-Okang Dukuzumurenyi 28 Views • 5 years ago

Probability is the examination of uncertain processes, but it's useful for far more than games of chance: http://www.gresham.ac.uk/lectu....res-and-events/proba

The modern theory of probability is considered to have begun in 1654 with an exchange of letters between Blaise Pascal and Pierre de Fermat, and has developed since then into the discipline which examines uncertain processes. For example, although on tossing a coin you have no idea whether you will obtain heads or tails we know that if you keep doing it then in the long run it is very likely that the proportion of heads will be close to a half. The lecture will discuss this and other examples of random processes e.g. random walks and Brownian motion.

The transcript and downloadable versions of the lecture are available from the Gresham College website: http://www.gresham.ac.uk/lectu....res-and-events/proba

Gresham College has been giving free public lectures since 1597. This tradition continues today with all of our five or so public lectures a week being made available for free download from our website. There are currently over 1,500 lectures free to access or download from the website.

The Elegant Universe: Episode 1 - Einstein's Dream Ambakisye-Okang Dukuzumurenyi 28 Views • 5 years ago

Today, Einstein's goal of combining the physical laws of the universe in one theory that explains it all is the Holy Grail of modern physics.
