Scientists discover hidden patterns of brain activity

Scientists discover hidden patterns of brain activity

If you look at a movie of neural activity with neural spiking here and here and here and here, it’s very difficult if not impossible to detect any pattern in the firing. But when you look at this pattern of firing through the filter algebraic topology, different structures emerge in terms of which families of […]

The beer with no head – Yummy Physics #4

The beer with no head – Yummy Physics #4

Barkeeper, one of your finest, frothiest beers, “s’il vous plait”. I want it so frothy that I get a big frothy milk-style moustache, Something I can really quaff and enjoy. I want maximum frothiness. What the f****! The beer foam is missing! The head is missing, the fluffy little hat! And you can’t have a […]

First Shifting Theorem – Problem 1 – Laplace Transform – Engineering Mathematics 3

Hello friends so today in this video we are going to find out the Laplace transform of sin 3t erased to minus 3t in to hyperbolic sin 4t now to get a Laplace transform of such term we do not have any standard formula which we can apply directly over here for so to get […]

Heterogeneous equilibrium | Chemical equilibrium | Chemistry | Khan Academy

Let’s say we wanted to figure out the equilibrium constant for the reaction boron trifluoride in the gaseous plus 3– so for every mole of this, we’re going to have 3 moles of H2O in the liquid state– and that’s in equilibrium. It’s going forward and backwards with 3 moles of hydrofluoric acid, so it’s […]

Which Cancers Can Be Treated With Immunotherapy? Ask a Scientist

Well in the early days of the development of immunotherapy the old saw was that melanoma was the immunogenic tumor and many immunotherapies like Interleukin-2 and Interferon were developed for melanoma. And indeed, melanoma is an immunogenic malignancy. It can spontaneously regress it responds to many different types of these treatments and there’s clear evidence […]

J. Krishnamurti – Ojai 1982 – Discussion with Scientists 3 – The need for security

The Nature of the Mind Part Three The Need for Security This is one of a series of dialogues between J Krishnamurti, David Bohm, Rupert Sheldrake, and John Hidley. The purpose of these discussions is to explore essential questions about the mind, what is psychological disorder, and what is required for fundamental psychological change. J […]

Refraction and Snell’s law | Geometric optics | Physics | Khan Academy

In the last couple of videos we talked about reflection. And that’s just the idea of the light rays bouncing off of a surface. And if the surface is smooth, the incident angle is going to be the same thing as the reflected angle. We saw that before, and those angles are measured relative to […]

Roger Penrose on Mathematical Physics

I’m Roger Penrose Emeritus Rouse Ball Professor of Mathematics at the University of Oxford The subject of Physics very much depends on mathematics and we have extremely good equations, theories to describe vast ranges of physical activity I mean, how particles move, how bodies move going back to Newton most of what we know about […]
