It seems obvious (even "intuitive") to us, but not to them. On the balance bike, one can just push along gently, but this new bike is bigger and heavier, and the gearing makes it harder. So my advice is to encourage him with an enthusiastic ... | I actually just taught my 5 y/o niece to ride without training wheels last weekend. First thing was that coming from training wheels she wasn't able to take off from being on her feet, rather the balance of the training wheels (which is easy). So baby step one was to hold her balanced on the bike during take off. My ph... | answer_2 |
19762 | Why are there species instead of a continuum of various animals? <sep> As I understand it, various animal traits have to evolve gradually, but what happens to the species that are "neither here nor there"? To put it differently, if a species evolved from another, it did so because it's somehow better, right? So why are... | Typically when both new and old species still exist it is because evolution pushed the new one into a different habitat or role. As a hypothetical example reef fish vs. deep water fish and their relative size. Let's say deep water fish evolved into reef fish, but we still have deep water fish. So there were deep water ... | Short answer <blockquote> Why are there species rather than a long continuum? </blockquote> Three important reasons I could think of are sex, non-uniform adaptive landscape and ancestry. Long answer I am not sure I'll answer your question so let me know if I miss your point or if I help! To start with, you might want t... | answer_1 |
19246 | Is there an 'anti-virus'? <sep> A virus spreads around and usually attaches itself to the host, multiplies & causes diseases. But is there something like an anti-virus? A single celled entity that does the opposite: spreads around 'kills' other viruses and/or cures diseases. Has anybody discovered something like it or ... | There is a "anti-virus," although many call it a virophage.In 2008, a paper in Nature was published about the observations of a new strain of a virus known as Acanthamoeba polyphaga mimivirus. This virus mainly attacks amoeba. It was discovered in 1992. It was one of the biggest viruses ever found.Later, a related viru... | There is no anti-virus to all viruses and there is no such anti-virus against a single virus yet, but there is immune response to virus. How efficient the immune response is then depends on many things. There is no perfect immune response. To develop such an antivirus that decreases viral load requires cooperation with... | answer_2 |
108052 | Why don't viruses reach broad concentration outdoors in a city like allergens? <sep> Why don't airborne viruses reach concentrations that infect most people vulnerable outdoors in a city the way an allergen can cause inflammation to everyone sensitive to it. Both are (often) microscopic airborne biological particles pr... | In another answer elsewhere on StackExchange, a poster estimated that there might be something like 100 g to 1 kg of SARS-CoV-2 virus worldwide, and that's an estimate of all the virus, including what remains in the bodies of infected individuals, not just what makes it to the outside world. I'm not certain of the accu... | 2, 4, 5, and 6. 6 being that the UV light (from the sun), fluctuations in temperature, humidity, wind etc mean that the virions are decayed relatively rapidly for most virus species. To address (1): In general a virus, such as SARS-CoV-2 or influenza is about 100 nanometres (0.1 micrometres (m)) in diameter, whereas a ... | answer_1 |
8 | How do I develop mobile applications for Bitcoin? <sep> I would like to develop a mobile Bitcoin application for the Android and iPhone platforms. What libraries and resources can I use? | Bitcoin client provides RPC calls which are in JSON, you could communicate via the RPC to make your app. | Currently there are only a few mobile apps that use the bitcoin protocol itself. Most communicate with a bitcoin client on a remote machine using the JSON API. Those few that do, rely on BitcoinJ which is a "selfish" implementation of bitcoin that runs in Java (handily the native language for Android apps). It's got a ... | answer_1 |
51871 | Have "molecular clusters" for azeotropes been identified? <sep> A different question about azeotropes got me thinking about this point again. Azeotropes have a very specific composition so it seems that the azeotrope ought to have some sort of physical structure. It seems to be a "molecular cluster" of some sort. The a... | No, in the absence of extra data, there is no reason to suppose that there is any vapor-phase cluster formation. Cluster formation in the gas phase would demand very, very strong departures from ideal-gas behavior. To the contrary, the ideal gas law is an excellent descriptor of gas phase mixtures of ethanol and water.... | In positive azeotropes for which the boiling point is less than the boiling points of any of the constituents the intermоlecular interaction of the different molecules is less than in the pure liquid phase. Therefore it is not very likely that clusters involving the different molecules will be formed. In negative azeot... | answer_2 |

19706 | How do I clean a pasta maker? <sep> I am experimenting with a home pasta maker, and after all the fun comes the cleaning up. My worries come from tiny bits of dry dough I find when I clean the machine. There always seem to be more every time I shake it, and they of course contain raw egg . On the instructions, it clear... | A couple of things that might help help on this one: If your machine has a few dried pasta crumbs on it, just leave it out to dry and knock / pick the dried dough out with a brush or a skewer. Don't worry too much about any crumbs of dried egg dough making you sick. You are going to boil whatever noodles you make for a... | I have a Kitchen Aide metal pasta maker!

I have made Ravioli for 45 years and cannot understand why a machine was made that you cannot take apart and clean the inside! We have tried a paper clip, straighten and sh... | answer_2 |
27745 | Can food be boiled "extra fast/hard" in water? <sep> Once water is boiling you can either leave the heat on quite high, or turn it down a bit so that it just keeps boiling. Apart from extra water vaporating, does this have any effect on the taste of food you're boiling (meat, vegetables, eggs, etc.)? With just common s... | In my experience, the most likely impact of a gentle boil vs. a furious rolling boil is going to be on texture of starchy foods, such as potatoes or other root vegetables, rather than flavor. I've found that a gentle simmer of potatoes will result in a mostly intact shape and consistent texture, whereas an aggressive b... | answer_2 | |

Given the encryption of $x_1, \dots, x_k$, the encrypted mean is defined as $$[\![\mu]\!] = \left(\prod_{i=1}^k c_i\right)^{k^{-1}\bmod N} r^N\bmod N^2$$ for some random $0<r<N$.

67135 | What is a "contradiction" in constructive logic? <sep> In Practical Foundations for Programming Languages, Robert Harper says <blockquote> If for a proposition to be true means to have a proof of it, what does it mean for a proposition to be false? It means that we have a refutation of it, showing that it cannot be pro... | It is immaterial whether we speak about constructive or classical logic in this situation. If you read your questions again, you will see that they apply to boths kinds. The only difference that we need to take notice of is the presentation of negation $\lnot A$. It can be presented in several ways classically, but int... | A contradiction is usually represented as $A \land \lnot A$. It's typical in intuitionistic logic to define $\lnot A$ as $A \Rightarrow \bot$. It's clear we can derive $\bot$ from $A \land \lnot A$. Ultimately, a contradiction will be a hypothetical derivation of $\bot$ as the very definition of $\lnot$ suggests. It wi... | answer_2 |
80168 | Why does this not prove $P\neq NP$? <sep> Fiorini, Massar, Pokutta, Tiwary and De Wolf (Exponential Lower Bounds for Polytopes in Combinatorial Optimization, Journal of the ACM 62(2):article 17, 2015; PDF, ArXiv) show any linear program that solves travelling salesman needs super-polynomially many constraints. Suppose ... | What Fiorini et al. show is the following: <blockquote> The TSP polytope $P_n$ over $n$ points is a polytope in $\binom{n}{2}$ dimensions whose vertices correspond to all Hamiltonian cycles in $K_n$ (the complete graph on $n$ vertices). (That is, it is the convex hull of the indicator vectors of all Hamiltonian cycles.... | What you're proposing isn't "a linear program for TSP", so it doesn't come into the scope of the proof.

I would like to cluster them using cosine similarity that puts similar objects together without needing to specify beforehand the number of clusters I expect.
