Most People Don't Understand Rainbows

Rainbows are curved optical phenomena resulting from the refraction and reflection of light in raindrops, with visibility dependent on the observer's angle, and can manifest in various forms such as double rainbows and glories.

  • Understanding Rainbows

    Rainbows are curved due to the angle of light refraction and reflection within raindrops. A single raindrop creates a cone of light that produces a rainbow effect, with different colors emerging at specific angles.

  • Key Optical Phenomena

    Light entering a raindrop slows down and bends due to refraction; some light reflects off the back surface, contributing to the rainbow's appearance.

  • Color Dispersion

    The maximum scattering angle for red light is about 42°, while for blue light, it's closer to 40°.

Simplest Math Problem No One Can Solve

The video explores the perplexing Collatz Conjecture, a mathematical problem involving the behavior of positive integers under simple rules, and delves into the challenges of proving or disproving it, the potential implications, and the parallels with other mathematical concepts.

  • Collatz Conjecture

    The Collatz Conjecture involves a simple iterative process applied to positive integers: if odd, multiply by three and add one; if even, divide by two.

  • Historical Context

    Proposed by Luther Collatz in the 1930s, it has various names including the Ulam conjecture and 3N+1 problem. Famous mathematician Paul Erdős remarked, "Mathematics is not yet ripe enough for such questions."

  • Hailstone Numbers

    The numbers generated by the Collatz process are termed hailstone numbers, as they rise and fall before reaching one. For example, starting with 27 leads to a peak of 9,232 before settling to one, taking 111 steps in total.

Why It Was Almost Impossible to Make the Blue LED

The development of blue LEDs, spearheaded by Shūji Nakamura in the 1990s, revolutionized lighting technology, enabling the creation of white light and earning him a Nobel Prize

  • The Birth of the LED

    First Visible LED: Created by Nick Holonyak in 1962, it glowed faint red. Green LED: Developed by Monsanto shortly after, but the quest for blue LEDs began.

  • Challenge of Blue LEDs

    Industry Race: Major companies like IBM, GE, and Bell Labs invested heavily but failed for decades. Importance of Blue: Blue LEDs were crucial for creating white light by mixing red, green, and blue.

  • Shūji Nakamura

    Nakamura's Background: Worked at Nichia, a struggling chemical company, and faced skepticism from superiors.

What Actually Happened To Amelia Earhart?

July 2, 1937, Earhart faced dire circumstances as her fuel was running low while flying over the Pacific Ocean. Earhart's route was the longest, following a path close to the Equator, making her final leg to Howland Island particularly challenging.

On These Questions, Smarter People Do Worse

Research indicates that for specific problems, higher intelligence correlates with poorer performance. The study involves a fictitious skin cream experiment where participants' reasoning about the results varies based on their numeracy skills.

How do QR codes work? (I built one myself to find out)

The speaker initially viewed QR codes as ugly and meaningless, preferring direct website links. They believed QR codes were a language for machines, not for humans. QR codes have become ubiquitous, used in various applications like tickets, menus, and advertising.

We Might Find Alien Life In 2299 Days

Europa's surface has few craters, suggesting geological activity that could erase impacts Evidence suggests a salty ocean beneath a thick ice crust, possibly containing twice the amount of water found on Earth.

Why Democracy Is Mathematically Impossible

Democracy may be fundamentally flawed: The methods used for electing leaders are described as "fundamentally irrational" and mathematically problematic. Used in 44 countries, including the U.S. and the U.K., it often results in a party winning without majority support.

What Everyone Gets Wrong About Planes

No keys or sensors: Plane doors can be opened if someone pulls the lever, but this is extremely rare in-flight. Self-preservation and common sense: Most passengers understand the dangers of opening a door at altitude.

Real Reason Robots Shouldn’t Look Like Humans

Future robots are expected to be soft, flexible, and adaptable for safer human interaction. Inspired by characters like Baymax from "Big Hero 6," these robots will differ from the metallic, humanoid figures like those from Boston Dynamics.
