BraveSpeaking: Real-world Physics

Noun idea that the universe began with a huge explosion between 10 and 20 billion years ago

Big Bang theory
The Big Bang theory says our universe was created when a tiny mass (billions X smaller than a proton) exploded and began expanding very rapidly into the stars and galaxies of today.

proton

Noun very small, positively charged particle that is part of the nucleus of an atom

equilibrium

Noun balance of opposing forces

equilibrium
Most of us have an inner equilibrium that allows us to perform extraordinary balancing acts. Still, getting up on the rope can be pretty scary!

frequency

Noun the number times that a sound wave is repeated in a period of time

frequency
Elephants communicate with each other by way of low frequency sound waves traveling through the ground. They can 'hear' rumbles with their feet over many kilometers!

inertia

Noun tendency of a body in straight line motion to stay in motion

Cats use a 'subtle mechanism' in which water sticks to the tip of the tongue and is pulled up into the mouth, taking advantage of the water’s inertia.

photosynthesis

Noun process by which carbon dioxide and water are converted into carbohydrates by green plants

Plant's photosynthesis machinery is tuned to absorb red and blue light most efficiently. In the future, plant factories will probably be "pinkhouses," glowing magenta from the mix of blue and red LEDs.

tune

Verb adjust for better performance

Plant's photosynthesis machinery is tuned to absorb red and blue light most efficiently. In the future, plant factories will probably be "pinkhouses," glowing magenta from the mix of blue and red LEDs.

absorb

Verb take in or soak up by chemical or physical action

Plant's photosynthesis machinery is tuned to absorb red and blue light most efficiently. In the future, plant factories will probably be "pinkhouses," glowing magenta from the mix of blue and red LEDs.

magenta

Noun a bright, deep purplish-red color

magenta
