| How do we know there's a Baryon asymmetry? Posted: 02 Jun 2018 05:24 AM PDT The way I understand it, is that we see only matter, and hardly any antimatter in the universe, and we don't understand where all the antimatter went that should have been created in the Big Bang as well, and this is called the Baryon asymmetry. However, couldn't this just be a statistical fluke? If you generate matter and antimatter approximately 50/50, and then annihilate it pairwise, you're always going to get a small amount of either matter or antimatter left over. Maybe that small amount is what we see today? As an example, let's say I have a fair coin, and do a million coin tosses. It's entirely plausible that I get eg. 500247 heads, and 499753 tails. When I strike out the heads against the tails, I have 494 heads, and no tails. For an observer who doesn't know how many tosses I did, how can he conclude from this number if the coin was fair?

| What does a velocity-time graph of someone in free-fall look like? Posted: 01 Jun 2018 07:24 PM PDT Since the acceleration due to gravity would be decreasing until reaching 0 at terminal velocity, meaning the acceleration-time graph would be a linear decrease, the velocity-time graph would be quadratic then linear once reaching the vertex right?

| Does this "wireless external antenna modification" actually work? Posted: 01 Jun 2018 09:15 PM PDT On step 5, the author claims that such a contraption can actually increase WiFi speed. Is that true? http://www.instructables.com/id/DIY-2G3G4G-Wireless-Cell-Phone-Signal-Booster/ [link] [comments]  |

| What does WIFI hardware look like? Posted: 01 Jun 2018 11:37 PM PDT I genuinely wonder what WIFI hardware looks like, the transmitting device and / or the receiving device. It's easy to find pictures of a "wifi device" but I want to zoom in as deep as possible into the actual hardware. And that happens to be quite difficult to find. I wouldn't even know how these pieces are called. Can anyone find pictures of this? [link] [comments]  |
| Would RBMK reactors be safe now with all we know about them? Posted: 01 Jun 2018 01:49 PM PDT After researching the Chernobyl disaster I can't help but come to the conclusion that the accident was caused by the operators not knowing the limitations of the reactor. Considering that these limitations are now well documented, I don't see how RBMK reactors would be unsafe. [link] [comments]  |
| Posted: 01 Jun 2018 07:11 AM PDT N-acetylcysteine (NAC) is used to treat acetaminophen overdose. NAC is also sold as a supplement and, by all appearances, seems to be readily available. Why can't the two be combined as a safer medication? Is there an established reason (medical, financial, or other practical concerns) why companies don't manufacture acetaminophen combined with NAC in one capsule. It seems like this combination would make Acetaminophen generally safer and would prevent (or at least mitigate) thousands of intentional and unintentional overdoses a year. [link] [comments]  |
