Vogelen met Arjan Dwarshuis
Met opa’s verrekijker tuurde Arjan Dwarshuis al als jongetje naar vogels. Die fascinatie bleef. De ouderlijke achtertuin werd de hele aardbol. In 2016 verbrak hij zelfs het wereldrecord om in één jaar tijd zoveel mogelijk verschillende vogelsoorten waar te nemen: hij telde er 6.852! Arjan Dwarshuis maakt de populaire Vogelspotcast, schreef diverse boeken en is een bevlogen ijveraar voor het belang van vogels. Hij vertelt over de vliegtechniek, voedselvoorkeuren, partnerkeuze, migratie, kortom over het leven van een aantal vogels én waarom zij zo waardevol zijn voor onze natuur en de biodiversiteit. Na afloop signeert hij zijn boeken.

The future of nuclear energy | Ferry Roelofs
Переглядів 1442 місяці тому
Nuclear energy captures our imagination: with just a tiny bit of nuclear fuel, one can produce an enormous amount of energy on a relatively small plot of land, with virtually no CO2 emission. However, nuclear energy also raises questions: how safe is it and what do we do with radioactive waste? Ir Ferry Roelofs, Account Manager Research NRG, takes us on a journey through the nuclear landscape: ...

    Science is up for sale due to ignorant people with a far too big voice.We know all the lists that are signed by so-called scientists pseudo-scientists. These people are unaware of the fact that sincere science goes evidence based (observations etc). However, i.m.o. it does not work by numbers as painfully (for some) demonstrated in history So scientists that sign these lists in news papers are at the least quite suspect or are avoiding professional suicide. If there are questions about environment, climate change they go "with the flow". I had a career in science based work ((virology, R&D in vaccines, veterinary diagnostics) and microbiological subjects). So I am not fully unfamiliar with the fields mentioned. I wish I attended your lecture since it felt very good to hear someone talk about subjects and not teach me a thing or two about how everything should be according to her/his opinion. A spree of comments and questions, caused by your pleasant talk, came to me but I will limit myself and so diminishing the possibility for me not to make sense. Thank you Dr. Herzberger for the brain stimulative talk.

    I love it when physicists draw far reaching conclusions from two theories that are just about as incompatible with each other as it's possible to imagine. I can't remember who it was who said "give me three free parameters and I can make an elephant, give me four and I can wiggling its trunk". This is pretty much how I view the Standard Model.

    Pure fantasy. No amount of mass would ever get to the pressures they postulate. It would vaporize into a plasma and radiate away long before their improbable speculation. became their impossible fantasy. Meanwhile the audience is agog at complex mathematical hypotheticals and think such a complicated logical game must be true in space and time reality. Piffle and fiddlesticks with a continental flare.

    Renormalisation = wiping something that is not right in the standard model under the carpet. Just to get away with those pesky infinite value, now with gravity the problem reemerges..yes thats why it should have been handled right from the start, it was wrong but nobody did anything to fix it. Only now they try to incorporate gravity in quantum physics, for decades it was just ignored, lets ignore one of the basic forces in the universe, what a great idea..I wonder for decades there has been little progress in science, not sure this guy is part of the problem or part of the solution, i have more faith in Roger Penrose, who says there's something not right with quantum physics, also the collapse of entangled particles is not caused by observation but caused by gravity. He is not very clear in his presentation.

    @1:06:00 right handed neutrino, it's so likely to be dark matter it's not funny. A massive RH neutrino would be about 4.8E8 GeV. Can only be stable if one LH neutrino is massless (so for it the oscillations are "turned off".) A highly predictive theory for dark matter. This one also due to Turok and Boyle. Dark matter could also be a "wormhole gas" (Kirillov & Savelova) but that could also be neutrino-ish. As fermions I figure neutrinos have to have internal wormhole topology anyways.

  • @Achrononmaster
    @Achrononmaster 5 місяців тому

    @1:05:00 't Hooft sketches the same idea, but done more rigorously by Turok and Boyle to answer why the cosmological constant value is so small. Neil Turok and Latham Boyle have found it *_is_* indeed a bit like an inverse of a large number. Performing a Lorentzian path integral and continuing analytically to complex time the entropy of the universe drops out as S=1/Λ (due to gravity the Hamiltonian contribution is zero, or exp(H=0)=1). Since our universe has a lot of matter and radiation is has sizeable entropy, and the most probable universe out of any ensemble is one with P∝exp(-1/Λ) close to 1, so Λ small. This Turok & Boyle result is not a causal account, since it's just statistical mechanics on an imaginary ensemble of possible universes, but a clue about what the source of Λ is. Turok describes it in an analogy as "like a chemical potential for spacetime volume." i.e., energy gained/lost by adding/losing one chemcial species, in the case of gravity that'd be the energy gain/lost on adding/losing an element of spacetime volume. Which is really, whe you think about it, the prosaic normal "explanation" for Λ, which is vacuum energy density. The source of vacuum energy density is the Planck scale topology. That's the answer. We do not know what it is because no one has developed a Planck microscope. ((They aught to find the Planck observatory in it's current graveyard orbit, bring it back down to the lab, hold it dead steady and just look down the other end in reverse.))
