- Marcelo Gleiser is a world-renowned theoretical physicist and award-winning writer and educator. He received his PhD in Theoretical Physics from King's College, University of London in 1986. After conducting postdoctoral research at Fermilab in Chicago and at the Institute of Theoretical Physics, University of California in Santa Barbara, he joined Dartmouth College in 1991. In 1994 he received the Presidential Faculty Fellows Award from the White House and the National Science Foundation, for his research in cosmology and dedication to teaching. He was tenured shortly after and is currently Professor of Physics and Astronomy and holder of the Appleton Professorship in Natural Philosophy. A Fellow and General Councilor of the American Physical Society, his research focuses mainly on the physics of the early universe and the emergence of complex structures in Nature, including life.

Prof. Gleiser is an awesome scientist and, firstly, a brazilian. Thank you for being a proud science supporter and a compatriot.
Adoro esse coroa. ❣ Inteligente e charmoso. ❣
Fantástico como sempre :")
Esse cara é fantástico 👏🏻👏🏻👏🏻
Thanks for sharing this, Andrew.
Muito bom ! Fantastico professor !
Loved it!
I was expecting something more advanced, or of a different insight, than this introductory explanation, which was good.
To bad it wasnt good enough for you. Were all so sorry and impressed with you.
Yeah why even write this comment? It’s not what you were looking ? close it and go look for something that’s more appropriate for you
Very good
To all people saying "firstly a Brazilian" or "He is Brazilian" or even just "Brazilian", please stop! So what he comes from our country? It only opens wide our eagerness to prove the world we are worth to participate the elite group - that only exists for shallow and silly comparisons such as this very one. The moment we leave this narrative and start to simply work on what must be worked and praise a scientist simply for what he is bringing despite where he's from, we will achieve the knowledge of the fact that we are for long already, part of this intelectual equality. Nelson Rodrigues argument at its finest.
Congrats
Marcelo faça um vídeo sobre a ida do homem a lua, na minha opinião esse evento não aconteceu.
Porque marcelo nao faz mais vídeos?
Yup!
Even facebook has a time line :P
I love the idea that we are all stars in some way! But I'm worried about the fact that we, provided by rare inteligent life, are not preserving neither ourselves.
Marcelo Gleiser is Brazilian, has with the native language Portuguese, and born in Rio de Janeiro which is a state that has a very strong accent. Do you think he speaks with an accent that you can not understand? What do you think of his English? I am Brazilian and I wonder what you think of our pronunciation in English.
Eu sinceramente acho que o importante é a comunicação. Converso normalmente com estrangeiros falando o português com sotaque. Se dá pra ser bem entendido, tudo bem. Talvez seja mais difícil um paulistano entender um sertanejo nordestino do que se fazer entender por ingleses e americanos com nosso inglês sulista ou nortista.
Ele tem um vocabulário que é invejável por qualquer nativo, pq vc tá preocupado com sotaque?
Eu interessado nos segredos do universo e outras pessoas no sotaque do marcelo , oxala tivessse 1 % do conhecimento do prof marcelo
A quick physics-centric view of the origin of life (biology gets into the details more). Very weak on philosophy, however (not his fault - and it isn't because he's a physicist and not a philosopher - it is because philosophy is very weak right now). For example in the end he says we must preserve intelligent life 'because it is rare'. This only scratches the surface of 'why is that important?', and thus it only scratches the surface of keeping us interested and motivated, and it certainly will not prevent future suicides due to depression (a good philosophy will) (religions don't cut it, since they do not deal in reality).
Thumbs up..who are here after getting in the news that Marcelo Gleiser has been awarded with 'Templaton Prize' worth 1.4 million
He's Brazilian
Who cares?
parabéns prof, Marcelo ,mostre ao mundo que no brasil tem gente que pensa...deixem as religiões de lado, para que a ciência produza mais mentes brilhantes.....
Deixar a religião de lado é deixar todas as pessoas tocadas por ela de lado, é excluir todo o trabalho de religiões sérias no combate à pobreza e à injustiça no mundo. Religião e ciência são algo totalmente diferentes, e ambas excepcionais, e não antíteses uma da outra.
A good basic introduction. I was expecting something with more meat. Knowledge that should be common sense by now. A bit dated. You even get an joke from Woody Allen "if the universe is expanding why should I do my homework."
what is wrong with the audio
Space can stretch like rubber?! SO SPACE IS BUNGIE GUM, that has both properties or rubber and gum!!! *schwing!
Som tá ruim
Shit, this audio sucks! I wish I could watch Gleiser's speech...
Aliens
This is a good recitation of the popular secular model for cosmological origins. But, much like US public education, there was no mention the problems with these theories. For example, gas has pressure and the more it contracts the more pressure there is. As such, gas does not simply condense into stars. The origin of stars is still not explained. Furthermore, our planets are not simply the products of the accretion of the leftover bits of star formation (again, for which there is no satisfactory explanation) because planetary accretion has been shown to contradict the laws of physics. Essentially, the force of collision is far greater than the collective gravitation attraction until the colliding rocks are multi-kilometer in size. In other words, you cannot accrete from pebbles to planets. This is another problem that cosmologists are aware of, but don't talk about, because it shows how flimsy their purely naturalistic and materialistic theories really are.
