Limits of measurements… Limits of out self…

The limits of classical measurements of mechanical motion have been pushed beyond expectations in recent years. But the sensitivity that we can achieve using purely conventional means is limited. For example, Heisenberg’s uncertainty principle in quantum mechanics implies the presence of “measurement backaction”: the exact knowledge of the location of a particle invariably destroys any knowledge of its momentum, and thus of predicting any of its future locations.

Backaction-evading techniques are designed specifically to ‘sidestep’ Heisenberg’s uncertainty principle by carefully controlling what information is gained and what isn’t in a measurement, e.g. by measuring only the amplitude of an oscillator and ignoring its phase. In principle, such methods have unlimited sensitivity but at the cost of learning half of the available information.

Now, in an effort to improve the sensitivity of such measurements, the lab of Tobias Kippenberg at EPFL, working with scientists at the University of Cambridge and IBM Research — Zurich, have discovered novel dynamics that place unexpected constraints on the achievable sensitivity. Published in Physical Review X, the work shows that tiny deviations in the optical frequency together with deviations in the mechanical frequency, can have grave results — even in the absence of extraneous effects — as the mechanical oscillations begin to amplify out of control, mimicking the physics of what is called a “degenerate parametric oscillator.” (1)

The problem of measurement. An unsolvable problem. And yet, within our mania to understand everything we have missed that every unsolvable problem points only to the obvious: that the problem itself is wrong!

Trying to measure things. In a cosmos which cannot be measured.

Trying to observe things. In a cosmos not meant to be observed.

Trying to understand. In a cosmos which was never meant to be understood.

Destroyers of the world.

Trying to push through a veil we ourselves have set up.

We are the cosmos.

There is no cosmos.

Trying to understand our self. Without accepting our self.

Can’t you see?

There is no need to learn how to swim.

You are already deep in the water…

Virtual ‘universe machine’. Galaxy evolution. Understanding unicorns.

By creating millions of virtual universes and comparing them to observations of actual galaxies, researchers have made discoveries that present a powerful new approach for studying galaxy formation. (1)

A cosmos full of phenomena. Phenomena we try to understand. Because we imagine we can. A cosmos full of laws. Laws we expect to decipher because we imagine they are there.

Imagine a universe.

And you will understand your own!

What a wonderful place for children!

Imagining unicorns…

Don’t laugh.

They are not your creation.

You are theirs!

Chameleon theory (theories)… Everlasting worlds…

Supercomputer simulations of galaxies have shown that Einstein’s theory of General Relativity might not be the only way to explain how gravity works or how galaxies form.

Physicists at Durham University, UK, simulated the cosmos using an alternative model for gravity — f(R)-gravity, a so called Chameleon Theory.

The resulting images produced by the simulation show that galaxies like our Milky Way could still form in the universe even with different laws of gravity.

The findings show the viability of Chameleon Theory — so called because it changes behaviour according to the environment — as an alternative to General Relativity in explaining the formation of structures in the universe. (1)

Changing theories.

The same as any other theory.

And at the end the changing theory will be accused of plasticity.

At the end, the rigid theory will be accused of dogmatism.

But why change? Why stay the same?

Why not question your own existence?!

I am the voice of silence. The destroyer of worlds.

Look at me! I explain nothing!

And yet people worship me.

Fools.

Looking for gold.

And yet during the gold rush it was not the ones seeking gold who made rich.

But those who sold shovels.

Look at what is not in the theories.

And you will discover the unchanged essence of the world.

There, between words.

Whole worlds are speaking…

Measuring laws…

One of the fundamental physical constants, the ‘weak axial vector coupling constant’ (gA), has now been measured with very high precision for the first time. It is needed to explain nuclear fusion in the sun, to understand the formation of elements shortly after the Big Bang, or to understand important experiments in particle physics. With the help of sophisticated neutron experiments, the value of gA has now been determined with an accuracy of 0.04%. (1)

Trying to measure constants.

To formulate models.

Which need more constants.

Which we then have to measure.

Until we measure everything.

Until we have defined all constants.

What a stable world that would be.

Perfectly defined.

Perfectly modeled.

It is raining.

Let’s find shelter.

Come on.

And in that stable world.

A kid.

And in the fierce rain.

Takes a step forward.

Into the rain.

Laughing!

Ruining everything!

Non-water. Inside the dead forest.

Led by Professors Raffaele Mezzenga and Ehud Landau, a group of physicists and chemists from ETH Zurich and the University of Zurich have identified an unusual way to prevent water from forming ice crystals, so even at extreme sub-zero temperatures it retains the amorphous characteristics of a liquid.

In a first step, the researchers designed and synthesized a new class of lipids (fat molecules) to create a new form of “soft” biological matter known as a lipidic mesophase, by mixing those lipids with water. In the newly created material, the lipids spontaneously self-assemble and aggregate to form membranes. These membranes form a network of connected channels less than one nanometer in diameter. In this structure, there is no room in the narrow channels for water to form ice crystals, so it remains disordered even at extreme sub-zero temperatures. The lipids do not freeze either.

Using liquid helium, the researchers were able to cool a lipidic mesophase consisting of a chemically modified monoacylglycerol to a temperature as low as minus 263 degrees Celsius, which is a mere 10 degrees above the absolute zero temperature, and still no ice crystals formed. (1)

Water freezes at zero degrees.

Unless you mix it with something else.

But then, it is not water.

And it can freeze at lower temperatures.

Everything is what it is.

But it can change to something else.

At the end, all things freeze at the same temperature.

If they are the same.

Or at different. If they are not.

Nature doesn’t care.

In the deepest cold…

Under the heat of the summer sun…

There are no temperatures.

Just things which boil and freeze.

There are many paths inside the forest of existence.

Do you care about how Achilles will reach the turtle?

Possibilities.

There is nothing to compare anything with.

For everything is connected with everything.

And all measurements are just reflections in the mirror.

Potential.

At the end you will be in the clearing…

Only to realize that the clearing is you.

Consumed by fire.

Breathing cold air…
