The greatest mystery in physics is probably how particle physics and gravity can be combined

in one model.

The mathematical structure of "Lie-Group-E8"could help here.

It has symmetry properties and could bring about a uniform theory in physics - quasi

the "theory of everything", more specifically THE world formula par excellence!

Welcome to Clixoom Science & Fiction!

Here you'll find exciting science videos three times a week, subscribe to the channel, only

then you won't miss a video, a warm welcome.

It should describe all processes and states in the universe, from the smallest things

in the quantum range to the largest cosmic structures at all.

And a US physicist claims to have set it up.

What can this alleged "world formula" really do and what is behind it?

In the 1960s, physicists had already discovered that elementary particles with their different

properties such as mass and charge can be brought into a certain order.

These are the so-called Lie groups, i.e. structures in mathematics that have special symmetry

properties.

The simpler groups can be used to describe objects such as cones or cylinders.

Even if they are rotated, they look the same.

The so-called E8 structure is different; it is much more complex.

It comprises a total of 248 dimensions and this does not mean spatial dimensions, but

degrees of freedom.

Thus the variables of a system, with whose size change also the complete structure changes.

With their help, research teams have developed the standard model of elementary particle

physics over time.

Specifically, it consists of a combination of a total of three Lie groups in which all

known elementary particles and three of the fundamental forces are taken into account.

But one important thing is missing: gravity.

For a long time it was assumed that this problem would solve itself in the course of time:

Exactly, by the discoveries of a Lie group, which also does not exclude gravity.

But this did not happen and by other ideas for a uniform theory of physics the E8 theory

moved into the background.

In 2007, however, it hit the headlines again with researcher Antony Garrett Lisi of the

University of San Diego.

He filled the E8 structure with various known particles and forces; he then assigned hypothetical

particles to the 20 unoccupied points.

In a computer simulation he then rotated the structure.

The pattern results show how the particles and forces may interact.

The big thing about it is that these correspond to the measurement results in the real world.

Lisi: "At that moment my brain exploded when I saw the implications and the beauty of this

thing.

I thought, "Holy smoke, that's it."

For example, quarks placed themselves around gravitational electromagnetic particles - in

families of three particles each with the same properties, but different masses.

The standard model also describes these particles in the same way.

Lisi published his results under the title: "An extraordinary theory of everything".

Lisi particularly pointed out that his model does without strings; and that it is so "simple"

and "beautiful".

Lisi is sure that the universe is based on pure geometry.

But one thing is still outstanding: the final experimental proof, or at least solid evidence

of his theory.

This would be the case, for example, if the Large Hadron Collider near Geneva were to

detect the 20 particles that Lisi had filled its structure with.

Smaller indications of E8 symmetry have already been discovered in an experiment.

A research team from Oxford had cooled niobium and cobalt crystals to 0.4 degrees above absolute

zero.

The atoms formed long chains and the electrons behaved like small bar magnets due to their

spin, a kind of angular momentum of the particles.

And because of this, a pattern spontaneously formed when the research team applied a strong

magnetic field at right angles to the spin axes.

The surprise was great when it was discovered that the spins had arranged themselves according

to the E8 symmetry.

Why exactly and what is behind it - that is still a big mystery.

But it is exciting that E8 is not just a mathematical construct, but can actually be found in the

real world...

And another word about string theory, which has long eclipsed the E8 model due to its

brilliance: In any case, some physicists are of the opinion that the E8 model does not

contradict string theory at all, but only complements it.

We once reported here in detail about string theory, in which the elementary particles

assume different properties depending on the state of vibration.

In contrast to the E8 model, it does not exclude gravity - however, the oscillation of the

strings refers to up to 21 spatial dimensions - depending on the model.

In any case, both formulas together would unite the theory of relativity and quantum

theory into one - into a world formula of "quantum gravity".

But there is still a lot to be done, because there is no experimental proof yet for string

theory.

But there is also a hint in our video about this topic: Does our universe not exist?

Will String theory be proven soon?

How to Make Matcha À La Mode (Matcha Ice Cream) -Simple 1 minute recipe to make tasty green tea dish - Duration: 1:26.

I will show you how to make Matcha A La Mode.

A La Mode is French word meaning "in fashion" and describes a sweet dish with ice cream.

Matcha A La Mode is basically matcha with ice cream.

To make Matcha A La Mode, mix 1 tablespoon of matcha with ¼ cup of hot water with a

temperature of 175 degrees f (or 80 degree c) and whisk them until they form little bubbles.

You can use a bamboo whisk, electric whisk, Milk Frother or simply a metal whisk.

Here, I am using a Milk Frother. It takes about 30 seconds. When you are whisking manually

using a metal or bamboo whisk, you want to whisk for about one minute.

You can pour the whisked mixture over one scoop, two scoops or three scoops or more

of vanilla ice-cream. I am using Häagen-Dazs ice-cream which is my personal favorite. Their

vanilla flavor goes very well with the bitterness of matcha without covering much of the matcha

aroma.

Make sure to serve quickly after you pour the matcha because the hot matcha melts the

ice-cream quickly. The melting ice-cream is part of the sensation you want to enjoy with

this dish.

The Simple Way To 'Unlock' The MINOR Modes On Bass - Duration: 8:25.

How do the modes of the minor scale work? And are they any different to the modes of the major scale?

Are they related at all? And if so, how?

Hi, I'm Luke from Become A Bassist and in if you've ever asked yourself these questions

or wondered about the modes of the minor scale, then keep watching.

A funny thing happens when bass players learn the modes of the major scale and how they

work.

A lot of the time, rather than answering their questions, it just brings up MORE questions.

This is exactly what happened to an email subscriber of mind named Lasse who wrote to

me and asked:

"I have gone through your ultimate guide to the modes.

It really cleared up a lot of things for me!

But I have one question left: When the song is in a minor key, I guess that the major

scale modes don't fit.

What am I supposed to use then?

I really like the idea that with the major scale, the modes fit the chords perfectly.

I'm hoping that there is a similar way for minor keys"

This is a great question!

Now if you're not sure how the modes of the major scale work yet, then this lesson

probably won't make a lot of sense.

You really need to have that knowledge as a foundation, and if you need help, check

out my Ultimate Guide To The Modes For Bass that Lasse mentioned.

You'll learn exactly how the modes work, plus where exactly to use them, and it's

all jargon-free.

No needlessly complicated terms or explanations - just a simple way to master the modes on

bass.

To get it, just click the link in the description of this video, fill out the form on that page

and I'll send it straight to your email address, 100% free.

Right now though, let's tackle this question.

The good news, is that once you've put in the hard work of learning the major modes,

then you already know the minor modes!

If the song you're playing is in a minor key, you can still use the modes of the major

scale.

All you have to do is start in a different place in the scale.

For example, if you're in the key of G major, you'd have the notes G-A-B-C-D-E-F# and

G again, and from there, you could build out the chord scale: G major, A minor, B minor,

C major, D major, E minor, F# diminished and G major again.

And over these chords you'd play G Ionian, A Dorian, B Phrygian, C Lydian, D Mixolydian,

E Aeolian, F# Locrian and then G Ionian again up the top.

These are our major modes - if you already know this stuff, then this is just a review

for you.

So what does this have to do with the modes of the minor scale?

Well check this out.

If you look at the 6th mode of the major scale, you get Aeolian.

This sound [plays scale] The other name for Aeolian is just the natural minor scale.

A lot of the time, when people say that a song is in the key of whatever minor, this

is the home base - this Aeolian, this natural minor scale.

Any time you hear Aeolian, you can just think natural minor.

G Aeolian - that's just G natural minor.

B Aeolian?

Just B natural minor.

But if we go back to our E Aeolian and build everything from this E natural minor scale,

we'll get the minor modes on bass.

Check this out.

If our new home base is this E Aeolian scale, then we'll have the notes E, F#, G, A, B,

C, D and E again.

If we build out the chords using these notes we'll end up with E minor, F# Diminished,

G major, A Minor, B minor, C major, D major and E again, which means our modes will look

like this.

E Aeolian, F# Locrian, G Ionian, A Dorian, B Phrygian, C Lydian, D Mixolydian and E Aeolian

at the top again.

You'll notice that it's the exact same notes, same chords, same everything - we're

just now starting at a different point in the scale and in this case it gives us modes

for all the chords in the key of E minor.

So if you're in the key of E minor and any of the chords from that key come along, you

can now apply these same modes to those chords and know exactly what's going to work.

This also means that the key of E minor and G major are related, right?

They use the same notes, the same chords, the same modes - everything is the same.

This is where it gets interesting.

Every major key has a relative minor key - the minor key that uses the same notes as the

major key - and that also means that every minor key has a relative major key - the major

key that uses the same notes as the minor key.

We've just found out that E minor was the relative minor of G major and G major was

the relative major of E minor - they're a related pair of keys.

But you don't have to go through this whole modes process just to figure this out.

There's a much easier way.

So here's the formula for figuring out your relative keys.

If you're in a major key and want to find your relative minor, just go down 3 frets

from the root and that's it!

For example, if you're in the key of Bb major and want to find the relative minor,

just go down a minor 3rd.

In other words, go down 3 frets.

From Bb to A, Ab, G - so G minor would be the relative minor of Bb major.

If you're in a minor key and want to find the relative major, just do the reverse - go

up 3 frets from the root of the minor key.

So if you're playing a song in C# minor, just go up 1, 2, 3 - and you'll find that

E major is the relative major of C# minor.

E major and C# minor are a pair of relative keys.

Couldn't be simpler!

If you want another way to imagine it, think about pairing up Ionian modes and Aeolian

modes from the same key.

For example, if you know your D major modes really well, then you'll know that your

6th mode - your Aeolian, is B Aeolian.

So you could very quickly figure out that B minor is the relative minor of D major and

vice versa.

Like I said before though, if you don't understand your major modes, you'll probably

have a hard time trying to understand the minor modes since they're so closely related.

If things are still hazy for you, make sure you check out my free Ultimate Guide To The

Modes For Bass.

In it, you'll learn exactly how the modes work and where to use them, plus you'll

get 24 practice tracks that you can use to start mastering the modes today.

Just click the first link in the description of this video, fill out the form and I'll

send it straight to your inbox.

It's 100% free and 100% fun, so go ahead and get started with it today.

Now there are actually minor scales other than the natural minor, or Aeolian that do

exist.

These are scales like the harmonic minor and the melodic minor, which are much less common,

and they have all of their own modes and everything as well.

However, knowing the natural minor modes - the ones built from the Aeolian scale - will work

for you the majority of the time - unless you start playing music that's a bit more

harmonically complex.

To recap though, you learned all about the modes of the minor scale.

You learned that the modes of the minor scale and the modes of the major scale are the same,

just starting at different places within that scale.

If you start on the 6th mode, the Aeolian, that will give you the natural minor scale

and once you build out the modes from there, you'll notice they're the same as the

major modes, just starting at a different point within the scale.

You also learned how the major keys and minor keys are related and how to find both your

relative major - by going up 3 frets - and how to find your relative minor - by going

down 3 frets.

Thanks so much for watching - I really appreciate it.

Make sure to check out that guide on the site - I'm sure you'll get a ton out of it.

I'm Luke from Become A Bassist and I'll see you in another video soon.

Mario Capecchi - Simple Equipment, Monumental Experiments - Duration: 3:17.

The beauty about science is that it's always changing. The thing that changes is

technology - how do you do things. And sometimes the technology doesn't exist

to be able to do what you want to do and then you develop the technology. If you

can't do something figure out how to do it!

That required me to have a hypodermic

that was very very small and a microscope to be able to see the cells,

and then to be able to put the needle into the nucleus, and then to deliver the

DNA into the nucleus. And next to me was Larry Okun, a colleague, and he was

using an instrument to actually record electrical currents in a cell. I looked

at his apparatus and it looked pretty much like a hypodermic needle to me. And

so instead of having a needle to record electricity then I would have a needle

that then would be able to contain DNA, and I could put some pressure into this

needle and then use as a hypodermic to put into the nucleus of a cell.

The tip of the needle is so small that I can't see it under this microscope. The

needle is about a hundredth as big as a hair maybe one-thousandth, somewhere in that

range, so it's a very small needle and you have to be very careful with it

because if you touch it on something it explodes. So you can't just

bzoom! And the microscope is what we call an inverted microscope. It's

actually looking at the image from bottom up. And the reason for that

is that we want to be able to play up at above but see from below. So it was

the first time that somebody had actually taken DNA, put it into a cell

into the nucleus, and then shown that it functions.

You know, this allows us to put anything you want into a cell. Proteins, you know,

you name it! And so then that's lit up a a light bulb, bam! If I could do that,

for example, in a mouse embryo, whoo! I could change any gene I want!

Well I think the machine was the right tool simply because it works. You

know, for a while I carried this thing around in a suitcase. I'd

give a lecture and then afterwards I'd pull it out like the Fuller Brush man and

show my ware and then show them how to do it. And that was important because

if I develop a technology and I'm the only person that can utilize it, it's

worthless. You're seeing cells you but can move them around and here's your

needle, boom boom boom, and they and you're doing one one after another. I got pretty

good at this machine I could do about a thousand per hour, worked 10 hours, so I

could do about 10,000 a day. And so I had Patsy Cline turned up high-volume, I've

take a lot of coffee, I'm a coffee addict, so then I'm really hypered up and then I

can really go. It's just like a video game. This is an antique,

but it's a cute antique.

How to Create Awesome Passwords - Simple 3-Step Process (both with and without technology) - Duration: 7:00.

- We all know that we need better passwords

but it feels like too much trouble.

Thankfully, it doesn't have to be

as I'm gonna share with you in this guide

to creating better and more secure passwords.

Hi, I'm Josh, and we're gonna start this with a little quiz.

I want you to think of any one of your passwords,

be it your bank, your email,

anything that you can think of

and answer these four questions, yes or no.

First, is that password longer than 12 digits long?

Second, does that password contain uppercase,

lowercase, numbers, and letters?

Third, is that password unique,

meaning that it hasn't been used

on any other account that you have?

And fourth, has that password been changed

in the past six months?

Now if you answered no to even two of those questions,

you've failed, but that's okay, you are in good company.

Trust me, so many of us are in the same boat.

All that means is that we need to take a few extra moments

to secure ourselves online by creating better passwords.

And what I wanna do right now

is walk you through a three step process

to do that very quickly and very efficiently.

Step one, select a process to create new passwords.

And this is something that we need to do

before we start changing our passwords

is we need to select that process,

and let's lay some ground rules.

First of all, changing letters into symbols is not secure.

Changing password into password is not gonna cut it.

Likewise, if you can actually save your password

really easily, such as crazy monkey

with a capital C, an at instead of an A,

and a zero instead of an O,

again, that's a little too easy.

Whereas if I were to give you this password,

it would take me about 20 to 30 seconds for me

to explain the whole password to you

the capitals, the lowercase,

the symbols and the numbers.

That is a secure password and that's what we're aiming for

with all of our accounts.

Those kind of secure passwords.

Now before you get a little bit overwhelmed

by the idea of having to create all these passwords,

let me explain that it is a lot easier than you think.

There's a couple methods, some that rely on technology,

and some that you can do on your own.

Let's start with the ones that you can do on your own.

My favorite method for creating these secure passwords

is to use a poem or a line in a song

or a favorite line that you like,

whatever it is, and create a password out of that.

Let's take an example of the poem Jack and Jill.

If I were to take the first line of that poem

and turn it into a password, it might look like this.

Jack and Jill went up the hill

to fetch a pail of water.

And as you can see, this password

is more than 12 digits long,

it contains capitals, lowercase, numbers, symbols,

and it's unique, or at least it's unique for this.

How would you take and make this password unique

for all of your accounts?

Especially if you don't wanna be writing

all of these weird ones down

and having to come up with new ones every single time.

Well the way that I've gone about it

in some of the accounts that I've had is I've taken,

let's say I'm gonna create a password for Facebook.

I'll take the first letter of Facebook, an F,

put it at the beginning,

and then I'll take the last letter of Facebook, K,

and put it at the end.

And I'll do that for ever single one of the accounts

that I'm creating.

If it's gonna be Gmail then I'll have a G at the front

and an L at the end.

That creates a unique password for every single one of them.

Now, this is a much better method

than probably what you're currently doing,

but it isn't the most secure method.

The most secure method is to just create

randomness as much as you can without any sort of semblance

of what you could explain very easily

like I'm doing right here.

And that's where technology comes into play.

There's a lot of password managers.

I use a password manager myself called Dashlane.

There are a number of others you can try.

I've put links in the description below.

What these do is they have a password generator,

and you can find these even online as well.

They generate a password that is very long,

very hard to say, and you can just copy

and paste that password in.

Now how do you remember that password?

That's what we're gonna get to in step two.

The key right now is to set up a process

to create the passwords.

Is it something you're gonna do in your head,

or is it something you're gonna do using technology.

I recommend you use technology at this point,

but that is entirely up to you.

Step two, we need to create a way to store

these secure passwords.

Now the last thing you wanna be doing

is writing down all these passwords on a piece of paper

and having to bring that piece of paper

with you wherever you go or pull it out every time

that you need to sign in to one of your accounts.

So what's a way that you can do that?

Well I already shared with you one of the ways,

which is to create one that you can remember

and that is unique for every single one of the accounts.

The other way is to use, like I said, a password manager.

Now if you look, as I'm using this password manager,

I've created all of the different accounts

that I have, and there is a unique password

that is set up for every single one of these accounts.

And while I'm on my computer

it syncs with my phone and my tablet.

All of those passwords stay synced up

and it's behind a single master password

that I need to know.

For my phone it can be my finger print,

but for the computer I need to have a secure password

that I use that allows me to get in and add these passwords

whenever I'm signing in to all my accounts.

Alright, step three.

Now we need to systematically go through

all of our accounts and change our passwords.

And before you freak out

about how much time that might take,

let's first just say what's important

is to get your most sensitive accounts changed.

I would go through, get a piece of paper,

and list out the most sensitive accounts.

Those are the ones that

if someone were to have your password

and to be able to get into these accounts,

they could do irreparable damage to your credit

or to your identity.

I would spend one day just getting

all of those sensitive accounts their passwords changed

using either the method we talked about

or a password manager like Dashlane.

Once you do that, then you can go through

and maybe spend five to 10 minutes a day,

or just anytime you log in to this new account

like Facebook or Twitter or Pinterest,

these place where, yes, a secure password is good

but it's not absolutely going to destroy you

if somebody hacks into that account,

that's when you need to go through

and change all of those passwords as well.

It might take you a little while.

I just decided to sit down

with one or two hours and just knock it all out

so that I had secure passwords.

And if I have a password manager like Dashlane or others,

when I try to log in,

it will automatically input those passwords

so I don't have to go through and copy and paste.

The only thing I need to know

is my master key password for that account

which could be my fingerprint

or it could be the actual password on my computer.

So to recap you need to select a process

to create secure passwords,

to store those passwords securely,

and then to systematically change those passwords.

And that includes changing your sensitive account passwords

about every six months or less.

I hope this was helpful.

If so, give it a thumb's up.

Questions go in the comments below

and if you wanna see even more great videos

about how to secure yourself online,

you can find those here in these playlists.

Have a great week and stay secure.
