  1. Just found an interesting article on the BBC science pages about the CHEOPS Telescope being operational. Looks like there are some really interesting planets out there. Exciting times ahead. https://www.bbc.co.uk/news/science-environment-52307087 Great too that CoronaVIrus isn't going to get in the way of science such as this. Paul

  2. That is nonsense. Plenty of folks took it seriously, their pandemic responses teams activated early January. China shut down whole provinces and tanking their economy and risking unrest. That alone was a strong signal (and WHO raised their warning levels at the same time). I mean seriously, what would have been a warning sign if not that? Obviously China (as well as other countries hit by SARS) took it seriously at the latest toward the end of January (again, there was an unprecedented shutdown). Other countries, including US and Europe did not react until late February to March. Folks such as the RKI in Germany have acknowledged that they should have done more contact tracing, for example. In addition it is a weird cover up that managed to create perfectly predictive data. So far transmission rates, lethality, effects of age and comorbidity all seem to line up with data all over the world so either they new the correct numbers and fudged it to much or they covered up something that had no impact on our undersanding. In that case if something was covered up, what would it even theoretically be? Everything that happened in China is now happening elsewhere with the same intensity (or worse, depending on the response). So what is being covered up that so well matches all observations so far? I do not expect the Chinese government to be forthright, but it is silly to assume that this causing in poor responses elsewhere as, again everything that came out of China so far was shown to be fairly predictive. In addition to all that, there was also data coming out from countries that started early testing, so by February we also had range of strategies on display, including total lockdown (China), enhanced contact tracing eventually followed by testing (e.g. Taiwan, Singapore, Vietnam, South Korea). Well, or nothing.

  3. Pangaea is just the last of a series of super-continents that existed in the past. The land masses had collided and separated in ages prior to its formation. As far as an imbalance is concerned; The entire mass of the Earth's crust is 2.77e22 kg, which is just 1/72 the mass of the Earth. In addition, continental crust is actually less dense than oceanic crust. So while the crust is thicker under the continents, it doesn't weigh that much different per square mile than oceanic crust. Thirdly, even if there were a slight shift in the mass of the Earth, it wouldn't cause an " imbalance". The axis of rotation would just shift to pass through the new center of mass. It isn't like a washing machine drum which starts to shake the whole machine if the load is unbalanced. In this situation, the axis of rotation is fixed relative to the washing machine and can't shift in response to the center of mass change. Thus the whole washing machine moves in response. The Earth rotates freely in space and is not connected to something else like the drum is connected to the washing machine.

  4. I think withholding funding from the WHO during a pandemic may make Trump responsible for some US deaths: https://www.vox.com/2020/4/15/21222756/trump-halts-who-funding-coronavirus-pandemic In defending Trump's actions, Kellyanne Conway claimed that the WHO is too busy working on the other 18 COVID viruses to be effective in this one. Apparently, nobody told the WH that COVID-19 was named for the year it was discovered.

  5. Sorry guys. I am real bad with words, not a good first impression. Maybe someone here could direct me to some reading material to help me better understand Pangaea. What I would really like to know is what happened pre-Pangaea. What caused the giant land mass. Having a mass of land on one side of the earth with nothing but water on the other side, did that create unbalance? I know that science is always under attack from certain individuals, I am not one of those people. I love science. Although I am an uneducated electrician. I have spent my entire life studying all plants and animals, with a huge knowledge of reptiles and amphibians. LOL, I am not that person.

  6. We don't have the same immune system (the proportion of Ig are different, cytokine ....) I found a paper about H.pylori (it's a bacteria but ... it can be extrapolated for virus). https://www.ncbi.nlm.nih.gov/pmc/articles/PMC4606101/pdf/JIR2015-315957.pdf

  8. You can easily do it with them ruining shots. You just have to make a few photos from tripod, instead of just one *). Then in Photoshop you place one photo in background layer, other one in foreground layer, etc. with the rest, if more photos have been taken, and then use eraser tool. It reveals what is in below layer. It is kinda entertaining. Newer Photoshop versions can even do it automatically analyzing sequence of images. See this tutorial: *) I always do multiple shots of the same scene. Because one might be out of focus.

  9. A house sized asteroid, which usually spends most of its orbit out past Mars ( in the asteroid belt ), crossed Earth's orbit today, at closer separation than the moon. https://www.msn.com/en-ca/news/technology/newfound-house-sized-asteroid-2020-gh2-flies-past-earth-today/ar-BB12Gvdz?ocid=msedgntp And... Bmpbmp1975, DID NOT claim it was the end of the world. ( sorry Bmpbmp1975, I just couldn't resist )

  10. Not quite. R records the fact that the page has been accessed (Referenced) M records the fact that the page has been written to (Modified) So reading a page the first time will set the R flag Writing a page the first time will set the R and the M flag Neither of those control what is allowed, they just record what happened to the page. The read/write controls whether the page can be written to or not. Initially it is read only until it is written to

  11. maybe doctors can try https://en.wikipedia.org/wiki/Pulmonary_surfactant Composition ~40% dipalmitoylphosphatidylcholine (DPPC);[5] ~40% other phospholipids (PC);[5] ~10% surfactant proteins (SP-A, SP-B, SP-C and SP-D);[5] ~10% neutral lipids (Cholesterol);[5] Traces of other substances. tweaked it a bit in vitro to see the best composition or addition that can kill the virus
