Wow, “ For a photon, its entire existence is instantaneous. “ , that put things in perspective!
Ask Ethan #109: How do photons experience time?
“[L]ight takes about 8 minutes to travel from the sun to earth. Light travels at the speed of light. If you do that relativity kicks in. So my question is, how much time passes for the photons traveling? In other words, how much have the photons aged when the reach the earth? Thanks for considering this.”
Travel at any constant speed, at rest, slowly, or near the speed of light, and you’ll experience time passing at the same rate it always does: one second per second. If someone else is moving relative to you, they’ll see your clock run slow (and you’ll see theirs run slow) depending on how quickly you move relative to one another. But what about a photon, which moves at the speed of light? From your point of view, no matter what your motion is, you won’t see time pass for it at all, and it won’t even experience time! For a photon, its entire existence is instantaneous.
Got two Mongolian friends here at work if you want me to ask them? :)
Here’s my first attempt at Mongolian calligraphy.
I would greatly appreciate feedback.
This, wow!
Impressive artwork.
Dr. Greg Dunn (artist and neuroscientist) and Dr. Brian Edwards (artist and applied physicist) created Self Reflected to elucidate the nature of human consciousness, bridging the connection between the mysterious three pound macroscopic brain and the microscopic behavior of neurons. Self Reflected offers an unprecedented insight of the brain into itself, revealing through a technique called reflective microetching the enormous scope of beautiful and delicately balanced neural choreographies designed to reflect what is occurring in our own minds as we observe this work of art. Self Reflected was created to remind us that the most marvelous machine in the known universe is at the core of our being and is the root of our shared humanity.

beautiful.
Wow, it’s somehow really relaxing in this!
Koalas to the Max
Mike Lawler and Dave Radcliffe reminded me of this great goofy site: Koalas to the Max. 4x the fun of your usual dots site.
Beautiful!
This sketch was made by rotating point 1 around a circle, rotating point 2 around point 1, and then joining a line between point 1 and point 2. In the gif point 2 is traveling in the same direction as point 1. Point 1 is traveling at 1x, and point 2 is traveling at 2x. Following the gif are some of my favorite combinations of the periods:
Rotating same direction:
1x and 1x
1x and 2x
1x and 5x
2x and 1x
2x and 5x
5x and 8x
The last image is an array of all the varieties from 1x to 9x for each point.

Wow, I just love when science is put to practical use!
I love it when people take up Physics concepts and incorporate them into the realms of everyday life.
The Doppler effect (or Doppler shift) is the change in frequency of a wave for an observer moving relative to its source.
It is commonly observed in sound. When a car is approaching you, the pitch (frequency) of the car increases and when it recedes, the pitch decreases. right? This is the Doppler Shift in action.
Or to put it in TBBT verbatim - “ Neeeeoooowwwww!”
The Doppler Shift works with light exactly the same as with sound! Just as sound seems higher or lower in pitch as the object is moving towards or away from you, light appears higher in frequency (color) when the object is moving towards you, and lower in frequency/color when moving away from you. The order of colors/frequency of light that we can see is:
Lower Frequency Higher Frequency
red - orange - yellow - green - blue - violet
So a far away object moving quickly away from you would appear more reddish than if it were standing still. The same object moving quickly towards you would appear more bluish than if it were standing still.

In his final interview shot by filmmaker Errol Morris, Mandelbrot shares his love for math and how it led him to his wondrous discovery of fractals.
