Hi

Guess It’s my first toot

I just did a schematic mind-map of the latest evidence about the existence of God.

Brought to you by some random Jehovah's witnesses who stopped me in the street. Pretty strong argument.

Being #atheist is so relaxing.

Ok so yet another one of my old #poems. This one was again from about 6 years ago.

= The Angel with Cracked Wings =

Light pierces through wind torn holes.
My eyes ache adjusting to the light.
Shapes and figures barely formed.
A sweet scent calls me forward.
But I know nothing of the day;
like a blind man,
seeking the sight he once knew.

But it is not in the light one finds sight.
It is in the darkness.
Here the sightless have sight.
Those who see are lost.
In this place beauty is more than a word,
more than a thing to look upon.
It is the essence of our soul.
Our own personal angel.

Rise then!
Lift yourself up!
To the clouds where angels sing.
Embrace your wind torn wings and soar once more.
For only with a heavy heart shall you be bound to the dirt.
Fly ever higher towards the sun.
Embrace its life giving warmth;
and in this place,
your happiness,
your heart,
your love,
will know no bounds.

I'm not much of a poet, but I just found some of my old #poems and wanted to share. This is one of the first poems I ever attempted about 8 years ago.

=== Light On the Other Side ===

The heart of man is burnt and gray;
for all our greatness we lost our way.

All alone the blind prevail;
no more love and we will fail.

Honesty and integrity crumble;
kings of men fall and fumble.

Love is lost, people torn
we die everyday and never mourn.
But there is light in babies born.

Hope exists for those who love;
the light is in us, not from above.

Give of yourself and you will find;
the part of you greater than the mind.

-All my love to the reader,
Jeffrey Phillips Freeman

Today I'm attending a formal all you can eat event. \o/

However, my family-in-law insisted, I should refer to it as “wedding“. 🤷

Go tell the Spartans... “The 19th AU and 6th NZ were to hold the [Thermopylae] passes as long as possible, allowing the other units to withdraw. The Germans... met fierce resistance...& sustained considerable casualties. The Allies held out the entire day;”https://en.m.wikipedia.org/wiki/Battle_of_Greece#Hitler's_decision_to_attack_and_British_aid_to_Greece

I‘d like to support MASTODON. Is there any crowdfunding and if, where?

Fun with spoons

How do you find the center of mass for any given geometry even if you have no idea on how to solve this analytically?

a) You can try some numerics.
b) You build a 3D replica and try to balance it on your fingertip. Works pretty well for spoons. Take a spoon, try to balance it -> yep, you found the COM.

Some more physics. You balance that spoon and add some small perturbations. Does the spoon hold? Congratulations, you just found a stable minimum.

How to describe this mathematically? -> Taylor series.
Dirty way - do a Taylor series expansion of the equation of motion around your extremum. Try to solve the differential equation with an ansatz combining two exponentials, one with a negative sign in the exponent, one with a positive one and both with different coefficients. The coefficients depend on the initial conditions but the exponents come from the solution of the differential equation.
If the exponent is imaginary you get a linear combination of cosine and sine functions. Congrats! For small perturbations your system will oscillate around the minimum but not leave it. You found a stable (maybe local) minimum.
Your exponent is real. Damn you found an unstable maximum. Try again.

Oh, I haven't posted to this instance yet!

So I'm an audio engineer / musician / tech nerd type. I write a lot and try to do something creative every single day.

Hello! I am new.

Bye bye birdie
