### It's all relative

I'd like to think that I'm raising the bar on t-shirt design subjects. In my quest for new designs I run into obscure topics that really only appeal to a very niche audience in very specific fields. But as I mentioned, this journey of mine into creative directing AI down less travelled paths is providing me quite the education. Take Einstein's general theory of relativity, versus  his E=mc2 theory of relativity which is also know as special relativity (as in "it's so special.") Basically E is energy, m is mass, and c is the speed of light. So the "you're so special" theory of relative deals with the speed of light and something about the laws of physics being the same for all observers moving at the same rate in relation to each other.

But Einstein also had a general theory of relativity.  It extends the principle of relativity to include gravity and acceleration. It posits that gravity isn't a force, it is the product of mass and energy throwing a curveball with spacetime. The formula for the general theory of relativity isn't as easy to remember as E=mc2.  It is Gμν+Λgμν=c48πGTμν​ (which is about as intelligible to me as Klingon).  Gμν represents the spacetime curvature. Λ represents the cosmological constant or the energy that just hangs around in empty space. gμν​ is the metric tensor (the tool that allows us to measure distances and angles in space and time), G is the gravitational constant, c is the speed of light and Tμν​ is the stress-energy tensor (a mathematical object that describes how matter and energy are distributed in space and time).

You following me so far?

As I understand it (which is very little) general relativity gives a framework for understanding the dynamic nature of the cosmos including why the universe is expanding.  In that theory is the suggestion that time runs slower in stronger gravitational fields, light goes around really big objects and black holes are places where gravity is so strong that even light can't get out of them.

The important thing about general relativity is that it gave me an idea for a really bitchin' t-shirt design with Einstein dressed like a General.

And what else did I learn today?

"Rocket 69" was a song released in 1951 that sounded like it was about a rocket ship but it was really about very dirty sex (and I mean dirty sex in a very positive way that escaped the censors in the repressive 1950s).

I also learned about the Sri Yantra.

Sri Yantra is a mystical diagram used in Hinduism. It has nine interlocking triangles that surround a central point known as a bindu. These triangles represent the cosmos and the human body and are a symbol of the union of the masculine and feminine divine (so it kind of relates to "Rocket 69.") The Sri Yantra is used in mediation and worship to focus the mind and achieve spiritual insight. It is also used to invoke the goddess Lalita Tripura Sundari, the supreme deity in the Hindu Shakta tradition. She represents beauty, wisdom, and power.

I also incorporated a bowl of Udon into a t-shirt design.

So I think I've had a pretty profound and productive day.
