| Posted: 08 Nov 2021 04:01 AM PST Hi, Reddit! I've worked on archaeological sites around the world in Denmark, Germany, Greece, Syria, the United States, Madagascar, Easter Island (Rapanui) and the Outer Hebrides. I have been UK Archaeologist of the Year and am a Fellow of the British Academy. My research on Stonehenge over nearly 20 years has helped to transform our understanding of this enigmatic stone circle, including the discovery of a new henge, a settlement where Stonehenge's builders may have lived, and the quarries for Stonehenge's bluestones in the Preseli hills of west Wales. I've published 24 books on a wide variety of archaeological topics, but I really love being out doing fieldwork. You can follow more of my recent work on PBS' Secrets of the Dead episode, where my team and I painstakingly searched for the evidence that would fill in a 400-year gap in our knowledge of the site's bluestones. The episode reveals the original stones of Europe's most iconic Neolithic monument had a previous life before they were moved almost 155 miles from Wales to Salisbury Plain. I'll be ready to go at 3:00pm EST (20:00/8:00pm GMT), AMA! Username: /u/ArchaeologyUK2021 [link] [comments]  |

| Is there higher background radiation directly under the Aurora? Posted: 07 Nov 2021 11:03 PM PST If i'm not mistaken, earth's magnetic field deflect charged particles, and pushes them to the poles, creating the Auroras. Also if i'm not wrong, the background radiation can vary really highly from place to place, because it's affected by many variants. But is there any increase in the background radiation, if you stand right under the northern lights or the cosmic radiation level stay consistent? [link] [comments]  |

| Do mental health conditions make a person more susceptible to other illnesses? Posted: 07 Nov 2021 05:35 AM PST I've had a rough couple of years struggling with anxiety and depression. I've also been getting every cold going around, and I've had a cough for the past 5 months. So I was wondering if there is any correlation between poor mental health and physical health [link] [comments]  |
| Can you get severe covid after recovering from mild/asymptotic covid? Posted: 08 Nov 2021 01:47 AM PST If you react mildly to one covid infection could you expect further infections to be mild too? Do anyone have statistics of repeated infections? Let's assume that nothing major have happened in your life like getting depressed and fat in a year. [link] [comments]  |
| Why is there "degree" in temp scales? Posted: 07 Nov 2021 07:15 AM PST It's °C, °K, °F I know ° only from geometry. why not simply 20 C? [link] [comments]  |
| In a phased array, what are the factors limiting coherent and non coherent integration? Posted: 07 Nov 2021 06:59 PM PST I've read that when integrating radar pulses, the SNR gain when performing coherent integration is equal to the number of pulses integrated. In non-coherent integration (regardless of technique used), the snr gain is equal to only the square root of the number of pulses. I am curious why you'd ever use non coherent integration when coherent integration's gain is so much better. [link] [comments]  |
| Posted: 07 Nov 2021 11:32 PM PST Let's say you have headphones that can plan 100dB at maximum volume. If you set volume to 50% on your phone, does that mean, that headphones are playing now with 50dB or some other value, like 75dB. How does volume scale and how does it work? [link] [comments]  |
| Is the "packed sphere" graphic used to represent an atomic nucleus accurate? Posted: 07 Nov 2021 09:08 PM PST I know of course that the electron visualization of a "moon orbiting a planet" is totally incorrect, electrons are best visualized as clouds of probability. There are a ton of beautiful visualizations for these on various websites, including Falstad. There doesn't seem to be any information about atomic nuclei though. Are they best visualized as the classic "packed sphere"? Or should they be represented as a probability cloud also, and if so, what does that look like? Or do we simply not know? [link] [comments]  |
| what happens to ergocalciferol in the liver and kidneys?? Posted: 07 Nov 2021 09:04 PM PST cholecalciferol is converted to 25 hydroxyvitmain d and to calcitriol in liver and kidney respectively, but what happens to vitmain d2. according to https://pubchem.ncbi.nlm.nih.gov/compound/Calcitriol , "Calcitriol is a synthetic physiologically-active analog of vitamin D, specifically the vitamin D3 form." so what is the active form of vitamin d2 ??

| How did Coulomb Charge the Balls? Posted: 07 Nov 2021 04:16 PM PST I know Coulomb didn't know the exact charge of the pith balls he was using when determining Coulombs law with a torsion balance, only their relative charge. What I want to know is what method did he use to charge the balls? Was he just rubbing the balls an insulating material to get the balls to give up electrons? [link] [comments]  |
| How does a computer know it needs to use a float/how does it derive the mantissa? Posted: 07 Nov 2021 02:29 AM PST So, I've been educating myself about floating point numbers and I understand how a float is represented in binary. I understand that it uses a sign, a mantissa as the body of the number, and an exponent as the offset for the floating point. What I'm not putting together in my brain is: How can it perform mathematical operations on, say, two integers, and then come out with a float? Let's say we're dividing 1/3. I know how 1/3 as the decimal value .3333... would be represented as a floating point number, and I know how to make that conversion, but a computer doesn't know what .3333... is. Somewhere, it has to realize both "I can't perform this operation" and "the sign, mantissa and exponent to represent this floating point number are...". The resources I've found explaining how those things are derived is only ever deriving them FROM DECIMAL NUMBERS, which obviously, the computer can't actually understand or do anything with. How does this calculation, (1/3), happen programmatically? What are the "in between points" between telling a computer "divide 0b0001 by 0b0011" and ending up at the correct floating point number?
