If you want to know the past

 


“If you want to know the past,
to know what has caused you,
look at yourself in the PRESENT,
for that is the past’s effect.

If you want to know your future,
then look at yourself in the PRESENT,
for that is the cause of the future.”

… so worthwhile

We are at our very best, and we are happiest, when we are fully engaged in work we enjoy on the journey toward the goal we’ve established for ourselves.
It gives meaning to our time off and comfort to our sleep. It makes everything else in life so wonderful, so worthwhile.

Impossible Figures

Impossible Figures – Art by Oscar Reutersvärd
Oscar Reutersvärd (1915–2002), widely acknowledged as “the father of the impossible figure”, was a Swedish graphic artist who in 1934 pioneered the art of 3D drawings which may initially appear feasible, yet cannot be physically constructed. Born on November 29, 1915 in Stockholm, Sweden, he reportedly suffered from dyslexia and had difficulty estimating the distance and size of objects. But his family was artistic, and encouraged his painting and sculpture efforts.

Do these look possible to you?

Nikola Tesla

 

When we speak of man, we have a conception of humanity as a
whole, and before applying scientific methods to the investigation of
his movement we must accept this as a physical fact.
But can anyone doubt to-day that all the millions of individuals
and all the innumerable types and characters constitute an entity, a unit?
Though free to think and act, we are held together,
like the stars in the firmament, with ties inseparable.
These ties cannot be seen, but we can feel them.
I cut myself in the finger, and it pains me: this finger is a part of me.
I see a friend hurt, and it hurts me, too: my friend and I are one.
And now I see stricken down an enemy, a lump of matter which, of all the lumps
of matter in the universe, I care least for, and it still grieves me.
Does this not prove that each of us is only part of a whole?

Science, too, recognizes this connectedness of separate individuals,
though not quite in the same sense as it admits that the suns, planets,
and moons of a constellation are one body, and there can be no doubt
that it will be experimentally confirmed in times to come, when our
means and methods for investigating psychical and other states and
phenomena shall have been brought to great perfection. Still more:
this one human being lives on and on.
The individual is ephemeral, races and nations come and pass away,
but man remains.
Therein lies the profound difference between the individual and the whole.

Nikola Tesla 1856-1943

The particle physics of you


scienceisbeauty

Fourteen billion years ago, when the hot, dense speck that was our universe quickly expanded, all of the matter and antimatter that existed should have annihilated and left us nothing but energy. And yet, a small amount of matter survived.

We ended up with a world filled with particles. And not just any particles—particles whose masses and charges were just precise enough to allow human life. Here are a few facts about the particle physics of you that will get your electrons jumping.

Crab Supernova explosion

 

This is the coolest outer space animation ever. It shows the Crab Supernova explosion, happened in 1054, and its evolution into the remnant it is now – called the Crab Nebula. Basically a thousand years speeded up into less than a minute.

&nbsp
Modern understanding that the Crab Nebula was created by a supernova, an explosion of a massive supergiant star, dates to 1921 when Carl Otto Lampland announced he had seen changes in its structure. This eventually led to the conclusion that the creation of the Crab Nebula corresponds to the bright SN 1054 supernova recorded by Chinese astronomers in AD 1054. There is also a 13th-century Japanese reference to an appearance of a new or “guest” star in Meigetsuki. It was then so bright it was visible during the daytime for 23 days.

The fight or flight response

The fight-or-flight response is a physiological reaction that occurs in response to a perceived harmful event, attack, or threat to survival.

It was first described by Walter Bradford Cannon. His theory states that animals react to threats with a general discharge of the sympathetic nervous system, priming the animal for fighting or fleeing.

An evolutionary psychology explanation is that early animals had to react to threatening stimuli quickly and did not have time to psychologically and physically prepare themselves.

The fight or flight response provided them with the mechanisms to rapidly respond to threats against survival.

The universe never be the same

On November 25, 1915, 35-year-old Albert Einstein presented a series of equations to the Prussian Academy of Sciences. Einstein’s ideas came to be known as the general theory of relativity. The universe never be the same.
