Science has been progressing year by year and decade by decade.
Even in the last decade, we made so many advancements that you probably don't know them all.
So let's learn about these top 10 achievements from last decade,
and understand why they matter!
Some of them are small, some are big and some even revolutionary.
Hello friends, I'm Chandra and let's learn about these top 10 achievement from last decade, one by one.
2009
Our decade began with an achievement in the same field with which it ended.
This year made our first programmable quantum computer.
Which despite its small size could compete with supercomputers!
Ideally if a supercomputer takes 10,000 years to complete a particular calculation,
that exact calculation can be done within hours or even minutes on a  quantum computer!
2009 may have been the beginning but the journey is still on.
2010
This year, we trapped the most precious thing the entire universe and made a beam out of it!
Anti-hydrogen,
Friends, it was a huge achievement
because till now we could create anti-particle but that would soon get in touch with matter and annihilate.
That was really a pain for storing it or doing extended research,
which was fixed by this achievement.
The new method makes use of magnetic field to successfully trap and levitate the anti-hydrogen
that it never gets in contact with the wall of container!
2011
Friends, you might know about this wierd world of quantum mechanics and it's wave particle duality
which is demonstrated in double slit experiment
when a photon passes through these slits without a detector, they always behave like a wave.
and creates this pattern on screen.
We call this "interference pattern".
But in the year 2011, we for the first time tracked a photon in this experiment
and observed how the photon was moving.
with the hope of making sense of wave-particle duality.
Obviously, since there a detector, it interacted with the photon. That interaction stored quantum information
in the detector.
Which is a valid quantum information leak (as everything outside potentially knows the quantum state).
Which is why, in this measurement, the photon was behaving like a particle so we could track it's position.
2012
This year was very special, apart from that movie as we're all alive.
But we had discovered higgs in this year.
Friends, if you don't know about Higgs then let me tell you that
Higgs is the reason why particles like electron, quark or neutrino have their mass!
But this was not the reason why "Higgs" was introduced.
Instead, Peter Higgs wanted to unify Quantum Electrodynamics and Quantum Flavordynamics.
and he had observed that a symmetry breaking of particular type could result in that unification
which he gave "electroweak theory"
2013
Ice Cube detector in antarctica discovered the neutrinos coming in from outer solar system!
This discovery matters because of neutrinos are what we call ghost particles, and they only interact via weak force, which is very rare.
Which is why theoretically an object made of neutrinos can pass right through you with even a problem!
2014
ESA succesfully landed their spacecraft Philae on Churyumov-Gerasimenko or 67P named comet
after which it started transmiting collected data
This ice beast is at 511 million km away from us coming with the speed of 55,000km/hour towards inner solar system.
2015
Friends, we teleported a photon using quantum entanglement this year.
Quantum Entanglement is that phenomenon which connects two quantum particle
in such a way that you can't describe one without the other.
Sorry to disappoint but friends we didn't really teleport anything.
Instead, we transferred the quantum properties of a photon namely spin and angular momentum.
and because of no-cloning theorem,
which says there can't be two xerox copies of same quantum information.
That led to the first photon changing it's quantum state and the second one capturing the first one's
Friends even though quantum entanglement led to transfer of quantum information
But until the site A (studying the first photon) doesn't give the confirmation to site B (having another partner of entanglement)
that the site A has done its part,
if site B does anything that will break the entanglement leading to no teleportation.
Which is why the second entangled pair wait until when before capturing the identity so, universal speed limit isn't broken.
But friends, don't get disappointed, that we can't use it for teleportation or faster than light communication.
But this is indeed something similar to wireless communication.
Like when the telegram was invented,
then we came to know of a method to wirelessly transfer classical unit of information i.e. "bit"
exactly like that, we'll use this to wirelessly transfer quantum unit of information i.e. "qbit"
2016 & 2017
Both these years were awesome as we discovered gravitational waves twice.
When a charge accelerates, that leads to the emission of electromagnetic wave.
which carries with it the information about change in position of charge.
Just like that the curvature in spacetime obeys universal speed limit,
whenever a massive object accelerates, that leads to emission of gravitational waves.
Which not only with it carries the information about change in position of that mass
but also shakes the spac e.
I mean elongate and stretch the space like this.
2018
This was the biggest achievement in solid state physics after 2004
Friends the strongest material known is graphene,
which is harder than diamond, yet elastic like rubber
200x stronger than steel, yet lighter than aluminium.
had something more to offer!
When MIT researcher Pablo Herrero twisted the two layers of atoms with an angle of 1.1 degrees,
he found something insane,
superconductivity!!!
Friends, superconductivity is that property which makes an object conduct electricity without energy source!
and all of this because of 
"zero resistance"
2019
Well, if didn't much about this year it would do, but still
this year we took the first image of a black hole,
This image belongs to the 55 million light-years away, galaxy M87's central black hole
Powehi
But that's not it, Google also announced the quantum supremacy backthen!
Actually google has succeded in making the first operational quantum computer
which can perform the task in 2.5 days which a supercomputer will take 10,000 years.!
Well, I don't know about scientific work, but it'll be heaven for gamers.
Friends, these were the top discoveries and achievements of the last decade.
What do you expect us to achieve in this decade?
Do tell us in comment section.
With that I say my good bye, till we meet again,.
till then stay curious, keep learning, Jai Hind.
