Lecture 28: Random Numbers - Richard Buckland UNSW (2008)

[@RobinSchlenga]

You certainly mean Quarks and Gluons :-) But you are talking about an interesting topic - most physicists think, that there is indeed an uncertainty inherent in nature, but on the other hand, there is tho so called "Bohmian Mechanics", based on Dirac's idea of a leading wave function - and this avoids uncertainty and is completely deterministic :-)

whatever you won't understand what i mean.. but the smallest particle possible in this world is indeed color dots forgot the name for em but they are Blue Yellow and Red and that is what drives our universe (Not the RGB don't get confused with Tv/computer color mixing) it could go further but its out of our reach.. Thats like saying if you were a animated AI on a computer that you could access your microprocessor you can't because you have no physical link to the other dimension.

Richard's security lectures will ever be available? it would be awesome

[@aljeno]

for lecture 27 if it's blocked in your country, find a proxy list for uk (it's not blocked there) and get youtube-dl, then use it to download lec 27 like this (replace proxy_ip & port) youtube-dl -f best --audio-format best --add-metadata --prefer-free-formats -i -console-title "27: Stress - Richard Buckland UNSW" --proxy proxy_ip:port

@ladovina100 very good point... thats why we need to seed the time in out system to srand() to provide somewhat random number.

The book is part of a box set. The Art of Computer Programming, Volumes 1-4A, Donald E. Knuth , ISBN-10: 0321751043, ISBN-13: 978-0321751041 - The Aristotle of Computer Science.

Hello, can i know the name of the book that you are using in this video ? best Regards

[@vedant6633]

I think he doesn't have any particular refrence book for the course, but yes he did mention Art of computer programming by Donal knuth a lot many times

Cool Teacher!!!

dude the reason its uncertain in the quantum field is because the tools used have very bad resolution to the level you are trying to reach the real universe (space is the same) if you don't have a powerful telescope u can't see far.. not the opposite to see deep into small things.. hell a bit of a wind/noise from atomic structures could trigger the randomness you call random even in a VACUUM chamber realize atoms are not squares they are round round = bad insulator

[@doh1959]

@Hax0rPr0n wrong it always comes out so the randomness reduces

[@PangeaMinor]

Why is there a 2/3 chance in the example around 36:57, and not 50/50?

Miyalys Sign The information about the game is insufficient, that's why I also didn't get it. If you know what is on the top then you have to guess the same on the underside. The chane that you are correct is 2/3 since you have two cards out of three with the same sides. This is called the Bertrand's box paradox.

right not idea that the smallest particle is color pigment is only judged by the human sense of sight.. what if we judge by the sense of hearing.. or tasting.. you cannot really tell which sense equals everything.. maybe we don't even have that sense that can tell the answer.. we are depending on our senses (hope u understand) i am not a man of big words but i am goddamn the most logical man in this world.

[@sspoke]

I have no idea how it cannot be common sense to rule out random? I believe the universe is a gaint virtual program where it runs of.. a based set of constants for some things and the rest are all equations which generate in your case a random but after all it's still just a equation.. I guess im not getting anywhere with you.. thats why time travel in the past in my mind is not existing.. but time travel to the future is like common sense to me.. that it will work... aka freezing/coma/slow/etc

[@sspoke]

nope its not random atomic radiation looks random because we don't look deep inside to find the cause everything has a cause that produces a effect.

[@doh1959]

iv experimented with random numbers there is some rule of physics goin on that as yet is unexplainable. let me explain and i know you will all disagree when a set of random numbers are created by a physical means you cannot stop the number appearing when a certain mathmatical equation is reached its fukin scary i am getting close to establishing the multiplier to get close to prediction in other words random is really not a true definition

[@txtmate16]

why are most of them asians?is this university located somewhere in asia?Dont get me wrong..im not being racist..i am an asian as well.

[@vedant6633]

In Australia

[@sspoke]

nothing is random PERIOD.. not even vibrations man only reason your quantum universe is based on uncertainty and chance is because your looking at the variables incorrectly.. man its hard to explain things to narrow minded people they will never understand.. they believe books more then they believe logic/common sense.

[@sspoke]

are you certain god didn't tell you to write that.. u cant be certain of anything dude cause its obvious everything is prewitten by the holy God
