| How are the digits of PI actually calculated? Posted: 15 Mar 2019 09:22 AM PDT How do we know that what we've calculated is correct? This Wikipedia page states that so-and-so of years past has calculated X digits of PI, but only Y are correct. Is there a formula for calculating the digits of PI? If so, is it something I can sit down and do on paper? This is the Wikipedia article I'm referencing above: https://en.wikipedia.org/wiki/Pi [link] [comments]  |

| How do zygotes gain totipotency? Posted: 16 Mar 2019 07:13 AM PDT So a zygote forms from the fertilization of an egg cell by a sperm, which are both specialized cells. What's happening on a molecular level that allows two specialized cells to fuse and become a totipotent cell? [link] [comments]  |
| Why is 'Candida Albicans' commonly referred to as a yeast infection, even though it is dimorphic? Posted: 15 Mar 2019 09:35 PM PDT Hi, I was in class the other day and the topic of Candida Albicans popped up. To my knowledge, it is a dimorphic fungi that causes what is referred to as 'yeast infection'. However, since it is dimorphic (i.e. containing hyphae), the name 'yeast infection' implies that the infection is strictly yeast (where moulds are the one consisting of hyphae). What is the reason for this, and does the fact it is dimorphic render the term yeast infection slightly inaccurate? Thanks for the help! [link] [comments]  |
| What is the nature of electrons when inside an atom? Posted: 15 Mar 2019 11:48 PM PDT I learned in highschool that the planetary model of the atom was incorrect and instead electrons occupy cloud-like orbitals around the nucleus. Whenever when this was taught to me, my teachers specified that the electron was a point-like particle whizzing around in the orbitals in a wave motion at such a fast speed that it appeared as a cloud. They said the cloud as a probabilistic "heat map" of where the point-like electron would be at any given moment in time; in fact one teacher even said that, while extremely unlikely, an electron could be on the other side of the universe at any given time but 99.99% of the time it'll be found somewhere in the cloud. I think I have been horribly misled about how electrons act inside an atom. Sources like this outright state that the orbital is the electron and I've found a few other places that say this as well. It's not entirely surprising that a scientific fact is being misunderstood; recently I found out that many of my physics teachers who told me that objects with mass couldn't reach the speed of light because their mass would increase towards infinity were actually incorrect. However I keep finding information that says exactly what my teachers were saying, even the wiki for atomic orbitals describes it in a similar fashion. So what is the true nature of electrons inside an atom? [link] [comments]  |
| Posted: 15 Mar 2019 11:01 AM PDT So for instance, I used to live in an apartment complex where you had to choose and separately pay for your own electricity provider. So for my apartment, I chose electricity provider G, but other apartments around me chose a number of other energy providers, T, C, and Q. All the electricity came to the apartment complex via the same power lines leading in, so how can anyone actually know that the electricity I paid for, going into my apartment, actually came from a power plant from provider G? Because my understanding is that electricity in power lines is pretty much the same no matter if it's generated from a dam, a coal plant, a nuclear plant, or a wind farm, so how is it differentiated, if at all?

| Was Pangea the only true supercontinent? Posted: 15 Mar 2019 06:17 PM PDT So I know that there were other supercontinents throughout history, but from what I read and understood it was the only continent that contained ALL of Earth's land mass. Is this correct? Or do one of the others get that award? [link] [comments]  |

| Posted: 15 Mar 2019 06:48 AM PDT When DNA is translated why is RNA used it seems like it would be easier to just use a copy of DNA and not have to have both "T" and "U" and only have to worry about having "T". Or am I missing some important reason as to why RNA is a better option to use? So instead you would have mDNA and tDNA and rDNA instead of mRNA, tRNA, and rRNA. I apologise if this is super obvious I'm somewhat new to biology. [link] [comments]  |
| There is pressure coming from em-radiation. Is there something similar for gravitational waves? Posted: 15 Mar 2019 11:10 AM PDT Photons can transfer momentum on charged particles, so defining a radiation pressure makes sense to me. I assume that gravitational waves only differ from em-radiation in the way they interact with particles. Also, general relativity exists only as a classical theory, so I think there is no known way to describe something like a "graviton", i. e. a quantum particle that relates to gravitation as an interaction. Anyway, do we have the tools to describe an exchange of momentum between gravitational waves and massive particles? [link] [comments]  |
