Coronavirus (COVID-19) Thread

34736 Curious to get your thoughts on this- why wasn't HIV considered a pandemic? As noted by wikipedia, some authors do: https://i.imgur.com/RxRlxgA.png The WHO does not, calling it instead a "global epidemic" , which from my naive perspective seems like exactly what you use the word pan...

Coronavirus (COVID-19) Thread

Linked on Discord. A simple but powerful visualization comparing the COVID-19 pandemic to others in more recent memory, by cumulative deaths from the date of outbreak (I'm not sure exactly how that date was determined, but it seems good enough.)   ujQ9Gy0LWiQ To think: COVID-19 is a mitigated  pande...

Coronavirus (COVID-19) Thread

It seems the autumn surge is upon us. Many countries in Europe and particularly the UK are back in crisis mode: Au9jnBumTVQ The situation here in the US is likewise alarming. Colder weather driving people indoors, pandemic fatigue, and the reopening of schools and universities is ushering in what I ...

Coronavirus (COVID-19) Thread

34706 In short, the effects, or manageability, of Covid-19 seems to correlate pretty strongly with population density. It does seem to be true. Using data as of yesterday (from  Worldometers ) for 50 US states, and plotting against the population density by land area (excluding lakes and rivers), a...

Coronavirus (COVID-19) Thread

NY Times "deaths above normal" page updated yesterday. Of all nations for which there are reliable overall data for deaths, it looks like Peru and Bolivia may have been the hardest hit by the virus so far.

34608 Have there been any studies done on the lungs? Lots.  Research on this virus and how it invades and affects the body has led to the most rapid explosion of scientific literature in the history of the world. I don't think it's an overstatement. Search on  Google Scholar  for "SARS-CoV-2 l...

Coronavirus (COVID-19) Thread

More information on how SARS-CoV-2 affects the heart.  Of particular note is how this distinguishes it from the rest in the family of coronaviruses that infect humans, which primarily affect the respiratory system. And of particular concern is that this no longer appears to be a rare occurrence, bu...

Israel Government approves a total lockdown starting Friday. Here we go again... a headline that is reminiscent of last spring. Israel is currently suffering their third surge in new cases, and it is the largest and steepest one yet, shooting them past the US and Brazil to become the 10th highest c...

Astrophotography

34584 But, can you imagine that in the future we can use satellites to picture space? We have been using satellites to do this for decades. The  Hubble Space Telescope, which launched in 1990, is perhaps the most well known for its beautiful images of galaxies and nebulae. But the history of space-...

34566 I collected some statistics on weekly deaths in Norway to compare 2020 with previous years.  Here's what I got: Very nice. Another reason I kind of wish I lived in Norway...  Your results also l ook consistent with the  analysis by the New York Times : https://i.imgur.com/ueCg7H1.png I've beg...

34546 Thanks guys!  How do you feel about Thorium? I feel quite positive about it! This PBS Space Time episode has a great overview of the technology and what makes it so much safer, while also reducing the lifetime of radioactive waste that is generated.

Population Growth and Sustainable Development

Good info and good sources. Nuclear is indeed cleaner and by sensible metrics less costly to the environment and human life than coal and most other methods of producing energy. It's just that if it goes wrong, it can go very wrong and the impacts are harder for the public to miss (also easier to ov...

34536 Like if you're flying fast towards a cliff, and a sound overtaking you from the behind will have its frequency shifted down, and when you hear the echo from the cliff a bit later, the same sound will be shifted up. Yes! Excellent analogy. 34534 hmmm this sounds a lot like how the sound of a t...

34528 What I don't quite catch here is that the black hole could make me see the redshifted things behind me in two different directions, once directly (behind) and once bent around the black hole (in front).  Therefore I would expect bands. Aye, I think I see your confusion, and it's my fault for ...

34524 If we were approaching a ring singularity in a spinning black hole would the tidal forces be as strong near the center? I believe that depends on the mass and the spin of the black hole. One could imagine a combination such that the ring singularity may be passed through with negligible tidal...
