Meenu Kumari on quantum chaos
Вставка
- Опубліковано 28 чер 2022
- A postdoctoral researcher at Perimeter Institute, Meenu Kumari is an explorer at the edge of quantum science. Her research explores open questions at the meeting points of quantum information, quantum foundations, and quantum matter. In this conversation with Lauren and Colin, she explains what it means to study the realm where quantum meets classical, and how we might harness the peculiar nature of the quantum realm to better understand chaos. She shares her unlikely path toward theoretical physics from a childhood in India, where she had to overcome social pressures and doubters to pursue an early love of science.
Conversations at the Perimeter is co-hosted by Perimeter Teaching Faculty member Lauren Hayward and journalist-turned-science communicator Colin Hunter. In each episode, they chat with a guest scientist about their research, their motivations, the challenges they encounter, and the drive that keeps them searching for answers.
The podcast is produced by the Perimeter Institute for Theoretical Physics, a not-for-profit, charitable organization supported by a unique public-private model, including the Governments of Ontario and Canada. Perimeter’s educational outreach initiatives, including Conversations at the Perimeter, are made possible in part by the support of donors like you.

Very excellent presentation - smart, articulate trio - and very good production values; especially the audio
I love Meenu Kumari's wonderful passion for the research she is engaging in. On a gentle closing note, this is the first PI talk where the hosts constantly (from start to finish) interrupted their valued guest. With that said, I am thankful for PI for inviting wonderful, insightful, and igniting speakers.
Mastering the art of conversation is difficult on both sides. The interruptions stuck out like sore thumbs but maybe it's a good thing that can be viewed as practice with friends because being interrupted can occur quite often at conferences and in everyday conversation. It can be a good thing for an expert to converse with non-experts too. It forces the expert out of technical language and jargon and makes them think a bit more about how to word things in a way that non-experts will understand. It might prove useful too if a young female journalist from the Butterflies Children's Media Center in Delhi, India wanted to interview a female theoretical physicist from India about her life and work.
My mom told me if I couldn't say something nice, to keep my mouth shut.
I'll do what mom said.
I love it when the host allows the guest to finish a thought.
Really proud of the Indian scientist. She shows real passion and understanding of the subject
Nice seeing your interview on perimeter. Great. I am proud of your progress. All the best for your future progress
Thanks for hosting her. From 22 -33 (roughly 11 min) , insightful discussion on the topic.
a wonderful interview and discussion. I am very curious about how quantum information theory could help resolve the 100 year old problem. There seems to be some work in the area. The ideas of Mark Van Ramsdonk, Leonard Susskind and Gerald H'ooft come to mind (holographic principle, quantum entanglement leading to emergence of space, ER = EPR -whatever that really means.
So often we actually find that previous people were not really "wrong". We find that there's simple more to the story.

I met her .
She is so kind and intelligent ❤
About the entanglement...can you measure the spins without collapsing the entanglement....ie to recover original spin superposition after the measurements...and good presentation btw.
if a particle's spin is measured then its entanglement gets transferred to the measuring apparatus, i think
Random: On the background chalkboard they actually had quantum gate diagrams. And someone has contact lenses now?
5:24 \ "explains supperposition" , Schrodinger made it up to show how weird it would be
Very difficult to understand the guest, closed captioning helps a lot
She studied physics form Manish Srivastava sir in gaya
Wonderful di. I am proud of you
I'm almost finished watching this video, and I'll be doggoned if I can figure out what these disadvantages were that your guest had to overcome.
She's a very smart woman. She is from a free country. She has a skin tone that supposedly makes her a "minority" in, and thus a recipient of the more beneficial policies of, the western academic world (among many other beneficial policy aspects of our society). This minority status is despite the fact that she is from the country with the second highest population in the world. She speaks English, so the availability of access to the unofficial official language in which science is presented and preserved, was clearly present.
Is it maybe because she wasn't raised in an extremely wealthy family? I don't know her background, but I do know that the people who score in the top two percent of standardized academic tests, tend to be offered scholarships in order to attract them to various institutions.
So, someone, please tell me why both of the hosts continue to reference her "disadvantages".
If you haven't derived my point, it's this: The way you not only allow such ridiculousness as the constant whining about disadvantages to continue to exist, but you actively cultivate such nonsense is something that I believed to be below the Perimeter Institute.
That "disadvantaged" horse stopped being capable of riding a long time ago. So, please, stop beating it to serve your own political agenda, whatever it might be today.
It really is shameful.
If “most” experiments confirm the theory of quantum mechanics. What method can be used to describe the anomalous results that don’t confirm quantum theory?
There seems not to be any difference between a flipped coin that is up in the air and its measurement when landing and a particle in superposition ( say up and down) and it's measurement. What is then so strange about that? It seems very acceptable. The difference seems only that the coinflip has always a 50% chance
It’s not been definitively shown that “Quantum States” exist - but they are perfect for calculating probabilities.
Excellent presentation of cutting edge quantum mechanics in simple terms .
Its not both it's a wave until it's a partical.
Thank you for sharing this conversation. I'm telling everyone at the Widget Factory that we are going to be making green widgets today!
Perhaps for entanglement the space property is simply gone.
yes in a way. entanglement information is non-local
When she says that quantum physics should merge with classical physics- that’s not true. The quantum world and quantum application on a macro scale is slated as not understood because it violates all known classical laws. It will not merge - it will bring to the forefront the erroneous nature of the classical model
Well the real world is de-facto unified, and the only true boundaries between states of matter and energy is just that of scale and distances on which they manifest, and which determines which specific combination of forces/fields that are at play in any given scenario. Nothing else suggests an existence of discrete and incongruent sets of natural laws concurrently existing in one reality.
Yall 2 got got a good job
Feeling proud of you maam
She is brilliant
Howdy.
The Theory of Everything, as to not be contradictory, would mean Theory of the Fundamentals of Everything.
Could you imagine the Theory of the Specifics of Everything? hahah.
I contend Gottfried Leibniz was correct about the fundamentals of our contingent universe and he just lacked 2022 verbiage/common knowledge.
More importantly is that humanity chose Isaac Newton's "real" universe, calculus, gravity, etc. This was a mistake. We need to correct this problem.
I've done my couch 🛋 warrior self's best impression of finishing what Leibniz started (with the intention of destroying what Newton started):
0D = (point); exact location only; non-composite substance.
(How ironic the symbol for Physics is the symbol for Metaphysics)
1D = line, straight; two points; composite substances
《0D (point) is exact location only; zero size; not a 'thing', not a 'part'; Monad》
"He is the invisible Spirit, of whom it is not right to think of him as a god, or something similar. For he is more than a god, since there is nothing above him, for no one lords it over him. For he does not exist in something inferior to him, since everything exists in him. For it is he who establishes himself. He is eternal, since he does not need anything. For he is total perfection. A being can have a relationship with a God but not the Monad as that would be a contradiction."
- The Apocryphon of John, 180 AD.
Monad (from Greek μονάς monas, "singularity" in turn from μόνος monos, "alone") refers, in cosmogony, to the Supreme Being, divinity or the totality of all things.
The concept was reportedly conceived by the Pythagoreans and may refer variously to a single source acting alone, or to an indivisible origin, or to both.
The concept was later adopted by other philosophers, such as Gottfried Wilhelm Leibniz, who referred to the monad as an elementary particle.
It had a geometric counterpart, which was debated and discussed contemporaneously by the same groups of people.
1st four dimensions are 0D, 1D, 2D, 3D ✅.
1st four dimensions are not 1D, 2D, 3D, 4D 🚫.
Human consciousness, mathematically, is identical to 4D quaternion algebra with w, x, y, z being "real/necessary" (0D, 1D, 2D, 3D) and i, j, k being "imaginary/contingent" (1D xi, 2D yj, 3D zk).
1D-9D 'contingent' universe has "conscious lifeforms" (1D xi, 2D yj, 3D zk)..."turning" 'time'. We're "turners", "to turn". Humanity is 3D zk.
"Turn" to what, you might ask. 5D is the center. All things and parts are drawn to the center, the whole.
[Contingent Universe]:
3 sets of 3 dimensions:
(1D-3D/4D-6D/7D-9D)
The illusory middle set (4D, 5D, 6D) is temporal. Id imagine we metaphysically create this middle set similar to a dimensional Venn Diagram with polarized lenses that we "turn" with our consciousness (which requires energy that we must consume i.e. calories to continue "to turn").
1D-3D set/7D-9D set overlap creating the temporal illusion of 4D-6D set.
1D, 2D, 3D = spatial composite
4D, 5D, 6D = temporal illusory
7D, 8D, 9D = spectra energies
1D, 2D, 3D line, width, height
4D, 5D, 6D length, breadth, depth
7D, 8D, 9D continuous, emission, absorption
Symmetry:
1D, 4D, 7D line, length, continuous
2D, 5D, 8D width, breadth, emission
3D, 6D, 9D height, depth, absorption
Time-relative food for thought:
According to theoretical physicist Carlo Rovelli, time is an illusion: our naive perception of its flow doesn't correspond to physical reality. Indeed, as Rovelli argues in The Order of Time, much more is illusory, including Isaac Newton's picture of a universally ticking clock.
Does time exist without space?
Time 'is' as space 'is' - part of a reference frame in which in ordered sequence you can touch, throw and eat apples.
Time cannot exist without space and the existence of time does require energy.
Time, then, has three levels, according to Leibniz:
(i) the atemporality or eternality of God;
(ii) the continuous immanent becoming-itself of the monad as entelechy;
(iii) time as the external framework of a chronology of “nows”
The difference between (ii) and (iii) is made clear by the account of the internal principle of change.
The real difference between the necessary being of God and the contingent, created finitude of a human being is the difference between (i) and (ii).
4D = architecture (structure)
5D = design (solution)
Our universal constants have convoluted answers. Leibniz's Law of Sufficient Reason fixes this.
FUNDAMENTALS > specifics, basically.
Our calculus is incorrect (Leibniz > Newton):
What is the difference between Newton and Leibniz calculus?
Newton's calculus is about functions.
Leibniz's calculus is about relations defined by constraints.
In Newton's calculus, there is (what would now be called) a limit built into every operation.
In Leibniz's calculus, the limit is a separate operation.
0D = (point)/not a 1D point:
[Math; Geometry]
A point is a 0-dimensional mathematical object which can be specified in -dimensional space using an n-tuple ( , , ..., ) consisting of. coordinates. In dimensions greater than or equal to two, points are sometimes considered synonymous with vectors and so points in n-dimensional space are sometimes called n-vectors.
[Math; 4D quaternion algebra]
A quaternion is a 4-tuple, which is a more concise representation than a rotation matrix. Its geo- metric meaning is also more obvious as the rotation axis and angle can be trivially recovered.
What do we mean by tuple?
In mathematics, a tuple is a finite ordered list (sequence) of elements. An n-tuple is a sequence (or ordered list) of n elements, where n is a non-negative integer. There is only one 0-tuple, referred to as the empty tuple. An n-tuple is defined inductively using the construction of an ordered pair.
In mathematics, a versor is a quaternion of norm one (a unit quaternion). The word is derived from Latin versare = "to turn" with the suffix -or forming a noun from the verb (i.e. versor = "the turner"). It was introduced by William Rowan Hamilton in the context of his quaternion theory.
How do you make a quaternion?
You can create an N-by-1 quaternion array by specifying an N-by-3 array of Euler angles in radians or degrees. Use the euler syntax to create a scalar quaternion using a 1-by-3 vector of Euler angles in radians.
[Biology]
Points, conjugate. (Science; Microscopy) The pair of points on the principal axis of a mirror or lens so located that light emitted from either point will be focused at the other. Related points in the object and image are located optically so that one is the image of the other.

Nice sistr..i m from Gaya,nd i know about you🇮🇳🇮🇳
Manish sir se physics padhi hain ye
right manish Srivastava gaya bihar
Right
The best part of the story is that she is from Gaya a very small town in the state of Bihar (India). She did her entire schooling from this small nondescript town (happens to be my hometown as well). So proud of her.
Meenu Kumari, well done, long may continue… you have learned quantum like others well to repeat it. Physic used to be real with classical physic. There was only head or tail, then came the con men and created a hallow coin weighted on one edge to stand presenting head and tail which operator decide which? This eliminated hard work and soon many became con men and made quantum popular. So physic became fiction. They took picture of starlight bent by sun’s corona matter (space dust & plasma) and lied telling public it was bent by gravity to establish GR. Today every thing sells with quantum label, even quantum crap. They pretend quantum cryptography make finance secure. At the same time banks hide the billions they loose on line. over 90% of current model of space and matter is fiction and none of you care because you get paid to be certified to repeat the dogmas not to do real science. If man becomes civilised and intelligent, they will be able to develop technology to see photon, electron, nuclei and their interaction with gravity as we have and replaced probability with fact and GR with real gravity.

You know you've played too many video games if you read "Quantum chads" rather than "Quantum chaos"
Bleepety blooo! Why don't you invent something real that we can be impressed by?
Yea this is just so bad I have to unsub sorry get actual scientists talking about actual reality and people will listen
The only chaos in Quantum is humanity's failure to understand it,
Why are you calling ignorance chaos.
