Ask Ethan: Are Quantum Fields Real?

“I would be very interested in a post about quantum fields. Are they generally/universally believed to be real and the most fundamental aspect of our universe or just a mathematical construct? I’ve read that there are 24 fundamental quantum fields: 12 fields for fermions and 12 for bosons. But I’ve also read about quantum fields for atoms, molecules, etc. How does that work? Does everything emerge from these 24 fields and their interactions?”

When you think about the Universe, you probably think about it in a very particular fashion. There’s spacetime: the backdrop upon which the matter in the Universe exists, and then there are particles and antiparticles, which make up everything we can conceive of in the cosmos. Only, the quantum nature of reality is very different from this intuitive picture, and quantum field theory goes a few steps farther than even the unintuitive pictures we have in our heads. What if Heisenberg uncertainty, the Pauli exclusion principle, wave-particle duality and more were all just manifestations of something very basic: quantum fields themselves?

Quantum fields, believe it or not, are the most real thing we know of in the Universe. Here’s the science of how they make up our Universe.

I love Gordon Ramsay so much.

He comes from a very poor family. His father was an alcoholic who beat him and his mother (he once poured hot tea over her and put her in hospital several times), his brother is a drug addict, he literally built an empire out of nothing.

He credits his mother as his biggest inspiration and often has her cooking in his shows.

When he left his first restaurant he pulled a successful Jerry Maguire - the entire kitchen staff went with him. That tells you what he’s like to work with.

He was one of the first to give a restaurant to a female chef.

He went to prison (Gordon Behind Bars) and taught inmates to bake and they opened a bakery (Bad Boys Bakery) that is still running. He hired one of them when he got out.

He did documentaries about the cruelty of shark hunting and cocaine. (when he discovered cocaine was used by his staff he didn’t fire anyone but made sure they are offered treatment)

His kids are a treasure.

He is always ALWAYS kind to servers.

When one of his partners (Marcus Wareing) wanted to leave they got into a fight and settled it in court, they no longer speak to each other but this is what Marcus said about him after the fight:

I feel bad that the first association to him for a lot of people is this shouty TV chef when he’s truly a wonderful person.

Oh and then there’s this:

this entire episode

someclevermoniker

never forget that the reason he’s “shouty and angry” on his tv show is that he’s yelling at people who ignore the rules of courtesy and food safety and basically feed their customers poison, something which would enrage any good person

I’m really glad people post stuff like this because honestly yes, the only thing I knew about Gordon Ramsey at first was that he swears like a sailor. It’s good to know that he’s a much more genuine person than that. This is probably also a good example of how television can shape our perceptions of people; TV producers are going to focus on what gets the most attention, not on what is necessarily best or most true about a person. It’s good to be mindful of that while watching reality shows and movies.

Not to mention he absolutely loves and nurtures talent. He cares about what he puts on a plate and will love you if you do the same. He shouts and curses at arrogance and stubbornness in grown adults who care more about making themselves look good than caring about the food they are preparing. There’s a clear difference. Gordon Ramsey is a treasure.

In Basque we don’t say “In love” , we say “maiteminduta” which roughly translates to “hurt by love”.

In Basque we don’t say “cancer”, we say “minbizia” which roughly translates to “intense pain” and I think it’s quite accurate in every sense.

In Basque we don’t say “give birth”, we say “erditu” which translates to “divide by two” and I think it’s beautiful.

In Basque we don’t say “moon” we say “Ilargi” which translates to “the light of the dead”.

In Basque we don’t say “desert”, we say “basamortu”, which roughly translates to “dead forest”.

In Basque we don’t say “free”, we say “musutruk” which translates to “in exchange of a kiss”. Example: Musutruk emango dizut. Translation: I’ll give it to you for free (I’ll give it to you in exchange of a kiss).

Explanation: The Basque language is an ancestral language spoken in the north of Spain and in the south of France. It’s the oldest language of Europe.

The world lost an amazing thinker today. Celebrated world-renowned physicist Stephen Hawking passed away on March 13th, 2018, at age 76.

Stephen William Hawking CH CBE FRS FRSA was an English theoretical physicist, cosmologist, author and Director of Research at the Centre for Theoretical Cosmology within the University of Cambridge.

Through a Quantum Tunnel

The phenomenon of quantum tunneling is best explained with a narrative:

You are at the bottom of a hill and need to roll a ball up the hill and down the other side.

Classically, the only option is to push the ball all the way up and roll it down. This would be a test of endurance and not to mention physically taxing.

But if you are in the quantum world you can dig a virtual hole and “probably” get to the other side of the mountain without expending as much energy as the classical ‘you’.

This behavior is called ‘tunneling’.

The reason why you would be able to pull this off in a quantum system is that there is a small probability of finding the particle in a certain location that extends to the other side of the hill.

Or if one were to put it more formally:

The wavefunction of the particle is a continous function and it cannot abruptly just collapse near the mountain/wall/barrier.

Instead it decays exponentially inside the barrier and extends onto the far side of the barrier as well.

This implies that there is a finite probability for the particle to tunnel through the barrier and get to the other side.

How big can the mountain be?

Since the wavefunction decays exponentially inside the barrier, it is no surprise that thinner the mountain, the better the chances for the particle to tunnel through.

Dependence on Barrier width

Can humans be tunneled through a barrier?

All this while, our discussion was primarily for simple quantum mechanical entities such as electrons, protons and so on.

And even for these systems merely increasing the barrier width would drastically bring down the probability.

Now if we were to scale this up to a system as complex as ours with billions and billions of atoms trying to tunnel through a wall couple of centimeters thick, nature just says ‘Sorry dude, Not gonna happen’.

Okay so maybe not the best way to break out of jail if you are a human I suppose.

But if you were a bouncing droplet, there might still be some hope. Check out the latest FYFD post on Hydrodynamic Quantum tunneling.

let me tell you something : you’re so talented

studygram | ask box

i’ve finished all my resmat homework today so im pretty happy, although it was just note taking i still enjoyed doing it hehe.

i should get a start on memorising english terms for my quiz this friday, maybe i’ll read them during the mornings

also i’ve cooked my own lunch but it looks and probably tastes horrible bc 1) i was cooking without my glasses 2) i just tossed it into a zip lock bag

oh well it’s still food im still going to eat it hehe

Some cool engineering please !!!

F1 engine playing Happy Birthday

When I was researching about F1 sometime ago, I stumbled upon this amazing video of the lotus team playing happy birthday on a F1 freaking engine!

The way this works is that the sheet music is taken and broken down into frequency and the milliseconds that it lasts for.

And the engine is turned on and off rapidly with different frequency tones to produce the tone i.e

OFF - f1 Hz - f1 Hz - OFF - f2 Hz - f2 Hz - f2 Hz- OFF …. (entire song)

The dynamic response of the F1 engine to changes in the throttle is what blew my mind. F1 cars are able to pull this off due to the extremely lightweight flywheel/general rotating assembly.

Imperial march on Floppy drive

Now you can do the same thing with motors as well. The motors can be revved up or down based on the frequency of the input.

Here’s the imperial march played on the floppy drive and Super Mario on the stepper motor:

What you are hearing is the tones made by the motor.

Notice the slider moving faster for higher frequency

If you are into Arduino and DIY projects you can play around with the ToneMelody package and piezo-buzzer to get a similar response.

Thanks for asking. Have a great day!
