Episode 4/13: Homochirality // A Course on Abiogenesis by Dr. James Tour

Diving into the science on homochirality, Dr. James Tour teaches the core chemistry concepts of enantiomers and chirality, exposing enormous challenges in the prebiotic synthesis and resolution of the molecules needed for life. By digging into the cited video's only provided reference, Dr. Tour puts ink on paper and shows how the devil is in the details when it comes to proper interpretation of the data. Finally, Dr. Tour touches on the stereoisomeric challenges facing synthetic chemists doing origin-of-life, prebiotic research.

Dr. Tour's passion is contagious. I love it.

You know what, the choice of music is growing on me. The classical music at the beginning gets us into a calm, serene, cerebral atmosphere of "let's calmly and rationally look at some solid scientific facts" and as the lecture progresses we gradually transition into Tour's headspace of high-energy funky techno outrage

[martyx]

Thank you, Dr. James Tour. We love you and may the Lord always bless you and keep you safe...

[richardfynn]

As a scientist myself, I have to say that Prof. Dave got a thorough scientific whipping here! This video really exposes the biased (desperate) agenda of the proponents of abiogenesis. Either Prof. Dave did not understand what he was talking about or he deliberately misrepresented the data

[robertabrown]

Thank you Dr Tour. Your words made me access my knowledge of chemistry terms from college. No wonder you are so successful in synthetic organic chemistry - you can see when something is wrong, and can specifically explain why.

[judgementiscoming]

God bless Dr Tour. Truth must triumph over lies and deceit.

I do not begin to claim understanding of the content addressed here, but thank God for his chosen individuals in his creation that are given the intelligence and ability to call out those with malice and evil intent in their hearts and work!

“Solved! Not solved. “. I laughed so hard.

Ive just come across this series after having heated discussions with my atheist-leaning agnostic partner about evolution and origin of life theories. This level of detail about the complexity further supports my arguments. Thank you for your thorough work. It's been a while since Ive had Chemistry but i was able to follow.

[MrWholphin]

The 24 elders (of revelation chapter 4) cast down their crowns saying:

"Worthy are You, our Lord and our God, to receive glory and honor and power; for You created all things, and because of Your will they existed, and were created."

I expect the substance of life will continue to confound materialists with its immense complexity, so far beyond human wisdom. This is a fruitful ministry brother Tour.

[rudyzoro]

You are my Hero Dr. Tour! We the believers cannot win this battle on earth, but the more important battle for heaven has already been won. In the end, we will say like apostle Paul did, 2 Tim 4:7-8: " I have fought the good fight, I have finished the race, I have kept the faith. Now there is in store for me the crown of righteousness, which the Lord, the righteous Judge, will award to me on that day—and not only to me, but also to all who have longed for his appearing." Amen and God Bless.

Details people, the details are important! Any time someone skips over details like it’s trivial with a subject like this, you always want to be skeptical... even if you don’t understand it (perhaps all the more reason).

[droe]

There are a lot of "Scientists" on YT and even documentaries on TV that make all sorts of claims. But when we get something like this video series, where we have an honest and highly trained and knowledgeable scientist critically analyzing claims of "scientists", it makes me even more suspicious and distrusting of these so-called scientists who are telling us what's what. Thank you Dr. Tours for taking the time to go through this and expose the inaccuracies and hyperbole of these so-called "scientists".

[ProfessorDaveExplains]

In this video James demonstrates his complete inability to comprehend stochastic processes by totally misrepresenting a paper I referenced, as well as research on homochirality in general by quote mining Donna Blackmond and pretending that a statement she made about symmetry breaking is somehow representative of the entire field. It's really disgusting and pathetic behavior. To learn about all the methods we are aware of by which enantiomerically pure biomolecules can arise via crystallization, which James deliberately does not discuss in this video, watch my response to this series linked below. Essentially everything in this series is James either ignoring research or totally misrepresenting it, so don't kid yourself by thinking you have the full story. Admit that you are just accepting Jim's authoritative tone because you are aligned with his ideology. Have some courage. Listen to a summary of the real science he doesn't want you to see.

[stevenmcnamara]

On behalf of all spiritual seekers worldwide your services to humanity are practically incalculable, but such are the workings of Divinity, who you represent. Thank you.

[ryanpalmquist]

You know what's really great about these videos from BOSS TOUR is even though I (and probably most of us) don't understand the really technical parts, or the processes, or the terminology... James does such a good job explaining EVERYTHING that you understand how unbelievably difficult (dare I say impossible) it would be for these things to happen BY CHANCE!!!! IT CAN HARDLY BE DONE AT ALL!!! Let alone naturally and by chance. I'm sorry... It takes way more faith then I can muster to believe anything other then a caring, loving God created us for His own purpose... Imagine.. if all the world had as much faith in God as "Professor" Dave and friends have in luck.

Dr. Tour, I watched the show on the science channel last night about the Perseverance Mars robot. The hype is worse than you state. The robot is looking for clues about possible life on Mars and in the middle of the show they talk about how life originated on Earth. To paraphrase - deep under the ocean molecules self assembled to form the first unicellular organisms, which somehow evolved to photosynthetic cells, produced oxygen, which in turn gave rise to the rich array of animals we have today, starting around 580 million years ago. Wow. You were not exaggerating to call in hype.

[salahelhaddad]

Yo Dr tour thank you for your dedication may God guide you to his path 💕

[danburlaqu]

That's what science is about. Checking the work and poking holes into someone hypothesis. Your work is crucial for scientific accuracy, and gods has nothing to do with it. Progress is always seen in the rear mirrors. Thank you for your time and expertise.

[jwyol]

Thank you for your work Dr. Tour, I pray God continues to greatly bless you and your family.
