If a tree falls in the forest does it make a sound? | Coma Niddy University
via comaniddy:
This episode of Coma Niddy University explores the idea of sound. Are sound vibrations and the sounds we hear the same thing? Or are they separate?
It depends on your perspective. The tree in the forest may be silent or screaming for some help.
I hypothesize that sound vibrations are separate from what we hear. What we hear is our brains’ interpretation of the information. Sound happens in our minds. As of now there is no evidence to support this idea. But it’s fun to think about.
So what do you think? Does the tree make a sound?

Silver Kills Germs! Nanotechnology Science - Coma Niddy University
Did you know that silver has antimicrobial abilities? The same silver that is in jewelry can kill germs, fungus and bacteria. Some scientists have developed nano-silver which is even more effective at blasting away germs. Learn all about here at Coma Niddy University!

Which is brighter? The red of a rose or the green of it’s leaves? Depending on the time of day this answer may change. Flowers can teach us about the physiology of our eyes. Explore with me as we learn about the Purkinje Effect.

http://www.youtube.com/pbsdigitalstudiosTake a look at my new video. It puts a twist on Valentine’s Day.
In 1819 Czech Physiologist Jan Evangelista Purkyne noticed that in daylight red flowers tend to stand out from their green leaves. He then noticed that the green leaves stood out more in low light situations. Purkyne’s simple observation of flowers led to an important discovery about human vision.
The AntiMatter Rap
via comaniddy:
According to Einstein’s equation, e=mc^2, matter and energy are the same. Energy can be transformed into matter and vice versa. However during the process antimatter is created as well.
Antimatter is awesome and raises a lot of questions. What happens when antimatter and matter meet? If antimatter and matter are made at the same time, where is all the antimatter? You can find out more in my new video - The AntiMatter Rap!

Why do Stars Twinkle? What are Pulsars?
via comaniddy:
Twinkle twinkle little star. Have you ever wondered what they are?
Stars twinkle because of refraction. Refraction is the bending of light. When light from the stars enters the Earth’s atmosphere the light bends. The air is moving all around making the light wobble. Our eyes have trouble seeing this wobble so instead it looks like a twinkle.
Pulsars twinkle for another reason. Pulsars are these crazy neutron stars that spin around like a figure skater. They shoot out all sorts of radiation including visible light. The light sweeps across space and appears as a pulsing light in our sky.
If you want to learn more, you can watch my video. It includes a refraction experiment and some cool visuals of pulsars!

Dark Side of the Moon: Fact or Fiction?
via comaniddy:
If you are familiar with Pink Floyd or the Transformers then you know about the Dark Side of the Moon. The idea is that one side of the Moon is permanently dark. How can this be?
Can the Moon truly have a Dark Side? The short answer is no.
The Moon spins like a top just like Earth. Over time sunlight sweeps across the Moon. So just like Earth, the Moon has night and day.
There is no permanent Dark Side of the Moon. However, there is something more interesting about the Moon. You can watch this week’s episode of The Big Bang Query to find out more about our Moon.
Comparing Mathematical Models to Musical Scores
via comaniddy:
Reading musical notes is the same as reading physics equations. Musicians can hear a song come to life as they read it. Musical scores to musicians are like mathematical models to physicists.
Mathematical models are used to describe everything in our universe. There are equations that describe the smallest events within an atom. There are equations that can describe very large events such as the motion of planets and the gravitational pull of black holes.
Think of these events as songs. The notes that compose the songs are the equations. There is one song that remains a mystery. That song is the origin of everything. How did the universe begin? What is everything made of?
String Theory just may be the equation/score to describe that event/song.
You can watch more video for more information.

Theory vs Hypothesis the Rap - Science Music Video
via comaniddy:
Have you ever noticed that people use the terms Theory and Hypothesis interchangeably? Most people say they have a Theory. They really mean that they have a Hypothesis.
My latest Science Music Video sheds some lyrical light on the situation.
Watch “Theory vs Hypothesis” to learn more!
Theory Tease Hypothesis
via comaniddy:
People were telling me that String Theory isn’t a theory.
People said that String Theory should be called String Hypothesis.
I had to untangle the situation.
So I went on a quest for more knowledge.
I share this knowledge by making a super fun awesome song.Watch the Video for a teaser.

Big Bang Query Ep. 7 - What is Quantum Entanglement?
via comaniddy:
The Quantum World is still a strange strange world. Particles always teach us something new.
One thing that we have learned is that when you bind two particles, they become entangled. Once entangled they share an unusual connection.
The weird part is that when you change one particle, its partner instantly changes as well. The particles can be close together or far apart and the effect still happens. What’s up with that?
Are you ready to get Entangled?
In this video, we explore the Quantum Entanglement and how it can improve our technology.Subscribe to my YouTube Channel Here: http://goo.gl/B2RPd
Big Bang Query Ep. 6 - Doppler Effect Science: Sound & Light
