Welcome back to Part 2 of Gravitational lenses on Whimsical Wavelengths. In part 2 we finally get to the real star of the show, strong gravitational lensing and the paper that was underlying the topic.

“Euclid: A complete Einstein ring in NGC 6505 “

A lot less to setup this time. No need to stretch this out like gravity stretches time.

But.....

How did gravity stop the reckless driver?

It pulled some strings… mainly the ones holding the car to the road.

Before everything gets pulled downhill, time to jump in Please welcome back Dr Georgios Vernardos!

Whimsical wavelengths is here again to show that it is useless to fight gravity.

Every time I have, it has brought me down.

To begin I'll mention Newtonian mechanics of gravity here in the show notes as it works really well for nearly all things within our solar system. But there are things that does not fit. Mercury’s orbit is one famous example. It gave the wrong prediction for the precession of Mercury's closest point to the sun.

Then Einstein developed a theory about space…

And it was about time!

It was a leap forward changing how we viewed the universe and how we would measure it.

It can be argued that this seminal work together with observations from Hubble on Galaxies existing outside of the Milky Way and expanding universe was the beginning of the modern age of cosmology .

Today we are going to get into one topic from relativity directly, gravitational lensing. To be fair to history, the idea that light traveling close to massive objects bends was actually first postulated by Newtonian mechanics of gravity.

And to get out from that enormous weight Dr Georgios Vernardos (Assistant Professor in Physics & Astronomy at Lehman College) has volunteered to come on the podcast. To get from relativity to gravitational lens and to tell the story correctly is hard to do in one episode. So I have planned this one as a pair! So no it is not time dilation due to the weighty subject

Today the topic should do more then whimsically tickle your ears, Today I have a guest to get the slobbering sensor in your mouth working. Yup buckle in for a flavorful ride!

So I guess definitions first. Food Science is a discipline that investigates food chemistry, food microbiology, physical, sensory, and nutritional properties of food. The discipline also gets into the process of making the food with respect to the manufacture, preservation, quality assurance, and development of food products.

If your favourite snack food is ummmm bet you can’t eat just one? It is practically guaranteed that a food scientist has been involved at some point of the process.

Dr Bryan Le joins the podcast to help us on this falvourful ride of whimsical wavelengths.

The papers discussed talking about Unami and how to get ingredient to be Kitchen Chemistry ready:

1. Hartl, Daniela M., Oliver Frank, Victoria S. Hänel, Vinzenz Heigl, Corinna Dawid, and Thomas F. Hofmann. "Isolation and Identification of Novel Taste-Modulating N 2-Guanosine 5′-Monophosphate Derivatives Generated by Maillard-Type Reactions." Journal of Agricultural and Food Chemistry 72, no. 25 (2024): 14284-14293.

2. Suess, Barbara, et al. "Human taste and umami receptor responses to chemosensorica generated by Maillard-type N 2-alkyl-and N 2-arylthiomethylation of guanosine 5′-monophosphates." Journal of Agricultural and Food Chemistry 62.47 (2014): 11429-11440.

There is lots you can do in science!! Including food science!

Thanks again Bryan for sending one to me! It's a good read (wish I had it before the episode!)
