Machine Learning Hands-on Learning By “Weights & Biases”

Founders of "Weights & Biases" Lukas and Chris are super successful already. The former company they created - Figure Eight provides a platform for people to label training data was sold to an Australian company for $300 million. Now they embarked on new adventure of this Weights & Biases, dedicated to educational Machine Learning. To … Continue reading Machine Learning Hands-on Learning By “Weights & Biases”

Laplace Transform

According to the wiki, "Laplace Transform" transforms a function of a real variable t (often time) to a function of a complex variables (complex frequency). The transform has many applications in science and engineering. It's similar to Fourier transform with a difference that Fourier transform of a function is a complex function of a real variable, while the Laplace … Continue reading Laplace Transform

Solve Twin Paradox by Applying Minkowski Space Geometry

According to Einstein's special relativity, time inflates while length contracts in a moving object with high speed comparable to light speed. So people accepts that if one goes out to outer space he/she will be younger relative to the people on earth. However, speed or velocity is a relative concept - we constantly fall back … Continue reading Solve Twin Paradox by Applying Minkowski Space Geometry

Journey To Learn The Glorious Maxwell Equations_4_Integral and Differentiation Forms

The Maxwell Equations contains four components. The first is about the electric field, the second is about the magnetic field, the third is about how the change electric field generates electricity, the last one is conversely, how the change of electric field or/and electric current generates magnetism. Previously, classical Newtonian physicists have deduced the following … Continue reading Journey To Learn The Glorious Maxwell Equations_4_Integral and Differentiation Forms
