Bob, Mr. Tubbs would be proud of you.

Promo>SM 😩

Very good. But if prior chosen badly (similar but wrong parameter say), you can into trouble cf with no prior (same totally random like flat line). One wonder …

😊

Excelente presentación

thank you for uploading this

I understand from his many friends and colleagues, Mr. Falkowski was a wonderful teacher and a dedicated oceanographer. Hope to apply his work on phytoplankton and atmospheric carbon sequestration in my own project to sequester an additional 20gigatons of Co2 by improving plankton colony nutrient sources. RIP Mr. Falkowski.

Your first view!

Amazing talk! Any chance I can get the source of the last image shown by Dr. Perryman? (38:42)

is there a video that discusses which situations are best for this approach

Matter and all the elements also water and hydrocarbons are created in the crust of theplanets, planets as universe are growing.

Universe is growing not expanding, look at Neal Adams an Samuel Carey Growing Earth teory. Earth was once smaller with continents together as one crust. look at asteroids which have strange forms becouse they are growing. Jupiter will become sun and ts moons will be its planets. its growing from inside, maybe interaction of antimatter and light and magnetic lines.

I wonder, if there was a single planet captured at the system‘s barycenter, would we be able to detect it?

Thanks for the video

Excellent introduction to the topic. Many Thanks

Too many conceptual jumps, leaving big blanks. Something as important and to the core of Bayesian Analysis as how to define the Likelihood function is left unexplained. And at 27:35 he says that Metropolis does not consider the evidence!! ABSURD!! It is precisely in the Likelihood definition where the evidence is considered.

the square shape could be replaced with a beautiful Fibonacci....

Love to watch your videos

I note 'Gaia DR3 astrometric orbit determination with Markov Chain Monte Carlo and Genetic Algorithms. Systems with stellar, substellar, and planetary mass companions' - in which the authors (July 2022) believe they have found 1000 or so exoplanets in the time-series astrometry data.

Great explanation, very helpful!!!

Thank you for your helping! 9:36 posterior 16:11 Bayes' theorem 29:18 Metropolis rule 40:35 walker(emcee)

Really helpful

Excellent presentation. Great speaker.

Video starts from @6:15

Quite clear and clever explanation. Thanks a lot for sharing.

Thank you!

wish i could see the pointer on the slides

This is a magnificent review of a very complex and exciting literature on the diversity of photosynthetic pathways across biology. Dr. Blankenship is clearly a leading light (sorry I could not resist) in this field and presents discoveries the span comparative genomics to the genetics of photosynthesis in microbes, to crystal structures of photosynthetic antenna and reaction centers, with nice astrobiology intersections as well. And world class mechanistic biochemistry from the crystal structural work as well. The best astrobiology talk I have ever seen because every attractive exoplanet for astrobiology rumination (as Carl Sagan would say, billions and billions of them) is illuminated by a parent star glowing somewhere between IR and UV. So photosynthesis is likely to be selected. My own bias is that the photosynthesis on exoplanets will use the same pigments and electron transfer pathways through proteins to the pumping of protons that we recognize on Earth. Not by convergent evolution but by the spread of the same Tree of Life between planetary systems, including Earth. This is not the astrobiology orthodoxy but I enjoy tweaking fields with excessive orthodoxy. We should look for chlorophyll and carotenoid pigment absorption or excitation lines on exoplanets----it takes a lot of chlorophyll to transform photons into biomass so it is abundant and has long lifetime excited states. Thank you Dr. Blankenship.

Excellent lecture!!!

Hello, Vielen Danke fur deine wirklich spannend fortrag. This was great!

He conveys a great point and I understand that the rigor is not the point of this video, but a statistician in me was screaming most of the time.

Too bad the audio got boinked.

Absolutely fantastic talk! Thanks a lot for this excellent introduction!

Thank you for the lecture, but where can we find the full recorded lecture?

MCMC starts 6:17

Absolutely love this presentation ! Writing my thesis now and I remembered how helpful this talk was and I'm so happy that they get uploaded. Also I completely forgot how on point the humor was ;D The dry humor got me so many times. Wonderful talk Vinesh, hope you see this comment :)

It would be nice to see a video on Nested Sampling. I've read some literature and coded some models in R, but still a little shaky with some things (e.g., dynamic nested sampling, extracting parameter samples proportional to posterior density [I'm getting good estimates with + - sd, but would prefer output similar to MCMC]). Throwing it out there since there are not a ton of resources, and because of the tease at the beginning :)

Did life originate on Earth only once? Could there have been more than one LUCA? More than one tree of life? If life could have originated more than once, must it necessarily have been DNA/RNA based? Could there have been another means of heredity and evolution? Why aren't there new trees of life "originating" now?

31:10 What the case (Metropolis rule) : P_trial=P_i (accept theta_i+1 = theta_i ?)

This is definitely not a beginner's guide. I know a little bit about bayes theorem, prior, posterior etc. But this Dr. Kipping ensured that i had to open up the books to sort out the mess he created in my mind. Definitely wont recommend to anyone.

Its interesting to know that there is certain degree of independence of the evolution of photosynthesis to that of plants alone. Realizing this may be useful in the prospect of increasing photosynthetic efficiency to meet future demands of human population from crop plants (like food and bioenergy).

Very clear and helpful lecture! Thank you!

A good explation by mam

The video mutes from 8:24 - 38:42 not sure if this is intentional but if not, please upload the unmuted version. this is a very interesting topic!

Amazing vids!! About to check out some more of your videos. Go and take a look at smzeus . c o m! I’ve been using it to promote my main channel and it helped me get my videos higher in the search results!

What about another unmanned space probe to Saturn's small icy oceanic moon, Enceladus?

you tried, anyway it's difficult ;)

I think the biggest problem of this video is that the presenter is using a laser pointer which we can’t see. So he says “this is this and this is that” and we never know what elements on the slides to follow. Also, the technical problems with things not showing up on slides.
