Few lessons from Bertrand Russell's History Of Western Philosophy✍️
An thread 🧵
Philosophy... is something intermediate between theology and science. Like theology, it consists of speculations on matters as to which definite knowledge has, so far, been unascertainable; but like science, it appeals to human reason rather than authority, whether that of tradition or that of revelation.
Modern philosophy begins with Descartes, whose fundamental certainty is the existence of himself and his thoughts, from which the external world is to be inferred. This was only the first stage in a development, through Berkeley and Kant, to Fichte, for whom everything is only an emanation of the ego. This was insanity, and from this extreme, philosophy has been attempting, ever since, to escape into the world of every-day common sense.
Maria Skłodowska-Curie's Legacy: The Only Person to Win Two Nobel Prizes in Two Different Sciences ✍️
A Thread 👇
1. Early Life and Passion for Science
Marie Curie, born Maria Salomea Skłodowska-Curie in Poland (1867), faced challenges as a woman pursuing education. Her passion for science led her to Paris, where she studied at the prestigious Sorbonne.
2. Discovery of Radioactivity
In 1898, alongside her husband Pierre Curie, she discovered polonium and radium, naming polonium after her native Poland. Her groundbreaking work opened a new field of study: radioactivity.

A Thread 👇
1. Wave-Particle Duality: Particles like electrons and photons exhibit both wave-like and particle-like behavior, as demonstrated in experiments like the double-slit experiment.
2. Quantum Entanglement: Two or more particles can become entangled, meaning the state of one particle is instantly connected to the state of the other, no matter the distance. Einstein famously called this "spooky action at a distance."
Richard Feynman was a brilliant physicist best known for his exceptional contributions to quantum mechanics and his captivating teaching style, among others.
Here are all of Feynman's Freely available Lectures at one place.

The Feynman Lectures on Physics are completely Free online. Read them here:
Paul Dirac was a pioneer of quantum mechanics and the first to predict antimatter, key to our understanding of the universe. He shared the 1933 Nobel Prize in Physics with Erwin Schrödinger for his work on atomic theory. In this image, he stands before a chalkboard filled with physics equations. ✍️
Richard Feynman
Richard Feynman was a celebrated physicist known for his work in quantum mechanics and particle physics. He won the 1965 Nobel Prize for his contributions to quantum electrodynamics. Feynman was also a captivating teacher, famous for his engaging chalkboard presentations, as seen in the image below. ✍️
