Jason Byrne and a superb communicator

Really???

If you remember it, you weren't drunk enough.

and he still can't account for the discrepancy between the second law of thermodynamics and his assertion, back in the 1990s , that "things can only get better"

were his band any good? genre? what did brian do lol? could imagine him doing some maiden kinda looks like bruce

or a politician!

@@oc2phish07 or a climate scientist.

And you never will.

!

Because theology is faith rather than fact

Breathe and hydrate.

Watch the one with Adam and Richard Dawkins. Interviews him brilliantly

Both committed to public education.

That part was genuinely funny.

+Miki Gatto NO ONE CARES!!!

Yep very satisfying to watch and listen. Better than fapping.

@@jamesl9040 cmon, we all know there's no chance Donald trump would be watching a video like this! Your blown! 💩💯💩

I was at Conway Hall that day. And totally loved it.

EVAN Parker No. I get the feeling you would like it to be wrong :) ? It is the most challenged and tested set of observations and conclusions concerning the facts of continual variation& CRITICAL SELECTION, nothing random about it, over time. Like a good goalkeeper, it hasnt let any in so far, 150 years and so far it is the best / only explanation, and frankly ONLY CHALLENGED BY IDIOTS IT HAPPENS and our understanding of how and why it happens is not going to suddenly be wrong, but like most things, occasionally just slightly not perfect.

Ask yourself if the theory we have on gravity is wrong and the answer is probably it’s wrong. Ask yourself if gravity still exists And the answer is most certainly although now I might have to add the caveat that it depends on the definition of gravity. Similarly the theory of evolution is most likely wrong to some extent but that does not mean there was no evolution.

dumaskhan yes

if you find the answer you could potentially master interstellar flight

Electrons are referred to as negative because of their behavior in an electric field. In an electric field, an electron will move from the negative pole to the positive pole, giving it a negative charge by convention.

Stephanie L Bullsemen :)

remarkably like a mad scientist.

for 1. that depends on a number of factors, DNA exists in different states, simplified these are called euchromatin and heterochromatin, euchromatin is accessible DNA heterochromatin is inaccessible (this is extremely dynamic). this allows in part the regulation of gene expression, though there are other factors to consider such as whether the gene is regulated by transcription factors and if those transcription factors are distance dependent.. there is no clear cut answer like with most genetics.

2. genes contain non-coding DNA which is spliced out and is actually incredibly important (hence the loss of the term junk DNA) variable splicing is what accounts for our incredibly complexity despite so few genes. that being said, coding DNA is in codons (three nucleotides) which each codon encodes an amino acid which builds towards the peptide chain that makes the protein and therefore it is possible to identify coding DNA from non-coding DNA. Non coding DNA is incredibly important for gene regulation in a whole host of incredible mechanisms and is actually far more fascinating than coding DNA to myself :)

As for length of a gene - how long is a piece of string? The length of the peptide chain the gene codes for determines the length of the gene (a triplet of base pairs coding for one amino acid.) The longer the peptide chain, the more bases required and hence the longer the gene. Some genes are affected by being transposed from one location to another and others not. Parts of the genetic code also control the expression of genes.

3 gold stars to SharpShotKills. No idea if the answers are right or not but they are full of long words.

It's called Posh lol

He actually said - 'life didn't occur in a sterile LAB'. but I get what you're saying. The more you think about it, the harder it is to imagine life first coming into existence without life already existing. We're so used to DNA being labelled as the building blocks of life that it seems instinctive to believe that DNA can't exist without life and life can't exist without DNA. Just another example of something Adam said early on- the answer to all the best scientific questions is 'we just don't know'.

I use "I don't know" more frequently as I get older. I think admitting my ignorance is very liberating.

David Renwick, I respect people for simply saying "the answer is, I don't know." No need wasting time speculating, and the honesty only makes that person look better. I've even gotten that reply from a CEO of a major corporation. Not a hint of intellectual pride!

Yes, its great fun to listen to a clever scientist and you know better than him . .

EXAMPLE: The matter that originally emitted the oldest CMBR photons that we are seeing now has a present distance of 46,000,000,000 light years from us, but when those photons first set out - the matter source of those photons was only 42,000,000 light-years away. [note 9 zeros & 6 zeros there]. So we are seeing radiation today from matter that is *NOW* 46B ly away, but that radiation was a lot, lot closer when it started out. As the photons travelled towards us through spacetime, spacetime itself was stretching. The distances I've mentioned above are not directly measured. They are derived from the observed red shift. This red shift is then plugged into an equation to derive the distance. Of course everything depends on the assumption that our model of the universe & inflation are correct, but I wouldn't be shocked if what we 'know' today is adjusted somewhat in the future... I stole my above figures from this Wiki on the *Observable Universe*:- en.wikipedia.org/wiki/Observable_universe *Warning* - it's a bit of a brain exploder - you need to look up & consider some of the terms used such as co-moving distance!

nightjarflying Thanks for that. So what you are saying is that we are observing something that was within 13.8 billion years away at it's onset but inflation was still in progress and had not completed? My brain hurts at the thought of the equations behind this stuff.

pilgrimpater Yes - you are kind of correct except your figure of "13.8 billion years away" is slightly wrong & needs the word "light" in there. There are also some other subtleties covered in the wiki. It's really a bit of an absurdist exercise to talk about the distance to an object *NOW* when the object is significantly far away & spacetime is *STILL* expanding. Cosmologists don't do this - they prefer to use geometrical diagrams with what are called "light cones" drawn in to better picture what is going on. Here is an example of a style of diagram invented 100 years ago to give you an idea: en.wikipedia.org/wiki/Minkowski_diagram please read the first paragraph & look at all the pictures. You have just looked at one of the *SIMPLE* old geometries that doesn't account for inflation - only for special relativity. If you want to find out what cosmologists draw these days you might want to book a bed in a mental hospital first! :)

nightjarflying Ta again. *"... except your figure of "13.8 billion years away" is slightly wrong & needs the word "light" in there."* Yes, that was just a typo. *"please read the first paragraph"* My limit, LOL. *"If you want to find out what cosmologists draw these days you might want to book a bed in a mental hospital first! :) "* That made me smile.

+pilgrimpater I have no idea, but I guess that one can mathematically extrapolate from given data set.

Is universe something like Saturn. Some asteroids moving around dark matter.

No, that's Ernest Rutherford (1871 - 1937), not Adam Rutherford.

A. Rutherford invented the wheel - Ruther"ford"

no thats ernest rutherford

Threapleton HolmesB Oh yes, DMT, the chemical released during death to stop us from panicking and being frightened that appears to be numbed if it is overused before that point. NO thanks. And the Pineal Gland, that helps our circadian rhythm (via melatonin regulation), and may affect sex hormones and can boost the effect of certain drugs by interfering with this sytem causing potent hallucinations. Hallucinations that is

Ahuaska isnt a drug it is two plants that the Shamans use in the Amazon forest. When people use it its done in the right enviroment they do Halluciante but its not the same as getting high on LSD the manufactured version. It releases DMT natually and connects you to your higher self. People say they have been released of emotional trauma and free of addictions compare what Stings says on this

Threapleton HolmesB I've taken ayahuasca/DMT+MAOI and to say it was a life-changing experience feels like an understatement. But just because you have an amazing subjective experience, it doesn't mean you have gained an objective understanding of the universe. Ayahuasca is not an intelligent life force. It is a substance which suspends the normal integration of a number of your brain functions, and this interruption causes you to perceive things in novel, alien ways. For people who are afflicted with rigid mental routines that they feel they cannot escape from (as is common among the depressed), this kind of trip out of their own minds can be enormously beneficial, as it introduces new perspectives on life and new patterns of thinking. It only seems like it's an intelligent life force because while you're on the drug, the non-integration under DMT leads to forms of primitive, magical thinking that I suspect probably inspired animistic religion. These kinds of drug have been consumed by people in many cultures for millennia - it hasn't provided them with scientific knowledge. What it may have done is provided some of them with psychological benefits, when taken in the right settings and in the right amounts. I think psychedelics (DMT, ibogaine, LSD, psilocybin) have enormous therapeutic potential, and it's a travesty that our foolish drug laws have blocked scientific research into them for so long. Thankfully, there are finally some psychopharmacologists studying them again as potential treatments in everything from addiction to depression to anxiety to PTSD, and there have been a number of promising findings.

A dream is a mild dmt trip. Tibetan monks can have a more intense experience by meditation. We've all had a dmt trip in our sleep but smoking it would be to intense for most people which can lead to a bad experience.

+Stephanie L Thank you so much for this intelligent answer. I completely agree with you on everything you said.

Agreed.

exactly what I thought too

Thank you, just what I was thinking.

You'll get an opposite impression from the Rutherford & Fry radio/podcast stuff from Radio 4: www.bbc.co.uk/programmes/b08svw8f

Lighten up, it's just his sense of humour. When he got asked questions he was very engaging with the people.

Agree, I see him at Dulwich last week with Ed Yong. This led me to here and I thought the same.

what a pathetically negative comment.

@@versioncity1 Thats right. He has done SO much for humanity. He has a real talent for teaching, telling complicated stuff so that one can understand.

Cox is vermin

Out of you and Brian, who do you think is the one that is holding back society from progressing? I'll give you a clue, it's fucking you, you filthy waste of fucking space.

boxxer221 hi Boxxer ..merry Xmas you blinkered sheep

Holding you back from enslavement to collectivism? Holding you back from being disarmed, like a slave? Holding you back from entitlements, like a slave? Holding you back from fake science? Holding you back from scientific method and eliminating the null hypothesis or shut up?

Where's your science you clown.....
