MegaFavNumbers: Planck Length (aka the smallest distance in the universe)
If a minimum length scale exists in the universe there's a very good chance it's equal to the Planck Length Lp, which is why 1/Lp = 6.187 x 10^34 is my choice for #MegaFavNumbers. The Planck Length is constructed by applying the technique of scaling analysis to three of the most fundamen

20 Subatomic Stories: Is the Planck length really the smallest?
A reasonable question of physics is if there is a smallest possible size and shortest duration and some scientists have claimed that there is and they are called the Planck length and Planck time. In this episode of Subatomic Stories, Fermilab’s Dr. Don Lincoln explains the truth of the P

Planck Scale | Where QFT and General Relativity Meet | Beyond the Standard Model
In this video, we will talk about the Planck scale. This includes the Planck mass, the Planck length, the Planck time, and so on. All of these "Planck-quantities" are constructed from fundamental physical constants, but where do these expressions come from? 00:00 Introduction 00:16 Defini

Using Dimensional Analysis to Find the Units of a Constant
This video shows you how to use dimensional analysis to find the units for constants in physics and chemistry equations. For example, why are the units for the gravitational constant (G) newtons, meters squared over kilograms squared. Dimensional analysis in physics is an important tool t
