In theory, quantum computers can do anything that a classical computer can. In practice, however, the quantumness in a quantum computer makes it nearly impossible to efficiently run some of the most important classical algorithms.

The traditional grade-school method for multiplication requires n^2 steps, where n is the number of digits of the numbers you’re multiplying. For millennia, mathematicians believed there wasn’t a more efficient approach.

But in 1960 mathematician Anatoly Karatsuba found a faster way. His method involved splitting long numbers into shorter numbers. To multiply two eight-digit numbers, for example, you would first split each into two four-digit numbers, then split each of these into two-digit numbers. You then do some operations on all the two-digit numbers and reconstitute the results into a final product. For multiplication involving large numbers, the Karatsuba method takes far fewer steps than the grade-school method.

When a classical computer runs the Karatsuba method, it deletes information as it goes. For example, after it reconstitutes the two-digit numbers into four-digit numbers, it forgets the two-digit numbers. All it cares about is the four-digit numbers themselves. But quantum computers can’t shed (forget) information.

Quantum computers perform calculations by manipulating “qubits” which are entangled with one another. This entanglement is what gives quantum computers their massive power, but it is the same property that makes (made) it impossible for them to run some algorithms which classical computers can execute with ease. It was only until some years ago that Craig Gidney, a software engineer at Google AI Quantum in Santa Barbara, California, described a quantum version of the Karatsuba algorithm. (1)

Think. Forget. Move on. Think again…

Know everything.

And you will need to forget.

Forget so that you can learn.

So that you know it all.

The path to light, passes through alleys of darkness.

And trusting the light can only lead to darkness, when the Sun sets down.

You need the Moon.

For it is only there, that you can see your eyes reflected…

Upon the silvery calm lake…

Sun breathing fire.

Light reflected on the Moon…

Cold light reflected on water…

Light passing through your eyes.

In the dead of the night,

You realize that you knew the Sun.

Stand still enough…

And you will listen to the cosmos being born…

Big data… Plants… Planets… Universe…

A group of Florida Museum of Natural History scientists has issued a “call to action” to use big data to tackle longstanding questions about plant diversity and evolution and forecast how plant life will fare on an increasingly human-dominated planet.

In a commentary published today in Nature Plants, the scientists urged their colleagues to take advantage of massive, open-access data resources in their research and help grow these resources by filling in remaining data gaps.

“Using big data to address major biodiversity issues at the global scale has enormous practical implications, ranging from conservation efforts to predicting and buffering the impacts of climate change,” said study author Doug Soltis, a Florida Museum curator and distinguished professor in the University of Florida department of biology. “The links between big data resources we see now were unimaginable just a decade ago. The time is ripe to leverage these tools and applications, not just for plants but for all groups of organisms”. (1)

Trying to understand the big picture.

By analyzing it all.

But you can never judge a book by reading all its pages.

You just read one. And then throw it away. Since you will already filled with the undying spirit of the author’s inspiration.

You can never judge a bottle of wine by drinking it all.

You just get a sip. And then spit it out. For you will be already full with the perfection of its taste and the distinctiveness of its aroma.

We cannot judge the cosmos by knowing everything about it. But only by sensing it to the point of remembering nothing about it.

Just see a butterfly fly.

Watch it die.

Sense eternity in its every dying breath…

Smelling the forest… A tree born…

Animals are much better at smelling a complex “soup” of odorants rather than a single pure ingredient, a study by the University of Sussex has revealed.

Prof Nowotny, Director of Research and Knowledge Exchange in the University of Sussex’s School of Engineering and Informatics, said: “Our study was looking at how olfactory receptors and brain structures cope with mixtures and single odorants. At first, we thought that mixtures would mean complications, but it turned out there was no extra complications and in fact, it’s usually easier to smell mixtures than single odorants and the sensing is also slightly faster. This wasn’t what we expected but this is what came out from our mathematical investigation”.

Prof Nowotny added: “Everything we take in from our environment is mixed smells, so it makes evolutionary sense that our olfactory systems would be better at those type of smells.” “Similarly, animals secrete odorant mixtures as communication signals (pheromones), so it is vital that they can quickly and accurately identify these chemical signals, so they can decode the message they are being sent”.

We were born in a forest.

Inside a vast universe.

Under the cold blue sky.

We were born in a forest.

But we can only see trees now.

We see many trees.

More and more trees.

Until there are no trees again.

Until we see the forest once more.

And it is only then…

In the deep dark forest…

That a small tree will be born again…

Staying awake. Sleeping more. Not understanding. Knowing everything…

New Michigan State University research suggested babies who are less active get less sleep, something new parents may want to consider when looking for possible solutions for the long, sleepless nights. Napping doesn’t help either. In fact, babies who slept less at night, yet napped more during the day, still weren’t able to get as much sleep overall as those who slept more at night. Plus, the tired tots weighed significantly more based on their length, indicating a potential risk for early onset obesity. (1)

In the beginning there was One.

And this is now broken.

Only those who remember that simple truth can see that there is nothing to see.

The universe is full of opposites.

And everything needs its opposite to be complete.

This is not a question to be answered.

But the answer which produces all questions.

Humans try to answer questions and understand things. But every new answer adds more questions, simply because from the beginning we have started travelling in the wrong direction. Our need to understand does not stem from the existence of questions to be answered, but from our resistance in accepting the fact that there are no questions in the first place.

There is no positive and negative charge, there are only particles.

There is no staying awake or sleeping, there is only living.

There is no living or dying, there is just being.

Stay awake more. And you will sleep more.

Do things. And you will need not to do anything.

Live a more intense life. And you will welcome death.

Ask more questions and provide more answers.

And you will get to know the value of doing neither…

For there is no knowing or not-knowing.

There is just…

Well, I’ll just stop there.

Only because I want to continue…

Proton. Mass. Higgs. Phantoms of science.

A proton’s mass is more just than the sum of its parts. And now scientists know just what accounts for the subatomic particle’s heft.

Protons are made up of even smaller particles called quarks, so you might expect that simply adding up the quarks’ masses should give you the proton’s mass. However, that sum is much too small to explain the proton’s bulk. And new, detailed calculations show that only 9 percent of the proton’s heft comes from the mass of constituent quarks. The rest of the proton’s mass comes from complicated effects occurring inside the particle, researchers report in the Nov. 23 Physical Review Letters.

Quarks get their masses from a process connected to the Higgs boson, an elementary particle first detected in 2012 (SN: 7/28/12, p. 5). But “the quark masses are tiny,” says study coauthor and theoretical physicist Keh-Fei Liu of the University of Kentucky in Lexington. So, for protons, the Higgs explanation falls short.

Instead, most of the proton’s 938 million electron volts of mass is due to complexities of quantum chromodynamics, or QCD, the theory which accounts for the churning of particles within the proton. (1)

Not the sum of its parts…

Can this be true in any way?

Everything is the sum of its parts. But some of the parts are invisible. And you need to know where to look for them. Why do we not see the QCD as part of the proton? Why don’t we see the soul as part of man? Why don’t we see man as part of the cosmos? Why don’t we see the cosmos as part of God?

Our ability to see the parts of things is intently related to our ability see just parts of those parts. For if we were able to see all the parts we would simply look at the whole…

It may sound weird, but only when we look at no parts at all will we be able to see them all at once…

How can anything be part of something?

To what else can everything be part of?

If not part of nothing?

See the proton.

There is no proton.

Can you see its parts now?
