In Starship Troopers, the motive of the humans to attack the Klendathu planet is that the "bugs" inhabitants of that planet allegedly launched a meteorite at Earth that destroyed Buenos Aires. The only evidence given is that the meteorites apparently originated in the Klendathu region of space. B...

I have an MTB that is quite old. The biggest chainring with 42 teeth is now done and I need a new one. It's a Shimano FCMC30, but it seems nobody is selling that new anymore.

Would you consider this a safe (white hat) link-building strategy? Our company has built 3D interactive models of some ecommerce products. We want to allow other sites to use these models in their own ecommerce stores, at no cost, so long as they provide a backlink to us. Reasons I think it's oka...

In Pearl's book "Causality" on page 124 (http://bayes.cs.ucla.edu/BOOK-2K/ch3-3.pdf) he says: A set of variables $Z$ satisfies the back-door criterion relative to an ordered pair $(X_i,X_j)$ in a DAG G if: (i) no node in $Z$ is a descendant of $X_i$; and (ii) $Z$ blocks every path between $X_i$ ...

As someone who conducts research that is unlikely to be of any relevance to the common man, I would like a little perspective on the impact that pure research plays in society, and how I can, in some sense, feel better about my research contributions. In a field such as pure mathematics, one can ...

I found that my former PhD advisor was still listing me as his student and he was the chair of my committee. I changed advisors a few years ago and left him. He didn't remain in my committee.

When I try to match for the string '3' in a case statement, it matches if the range goes up to '9', but not '10'. I'm guessing it has something to do with the triple equals operator, but I don't know the exact reason why it can be in the range, but not matched. Here is an IRB run documenting both...

I've studied electrostatics and we always use Coulomb's law to calculate the force on a particle due to another particle. In an atom there are many electrons and many protons, and if we "take a picture" of an atom, at any given moment, we should see something like this (which is possibly wrong, s...

In many textbooks, energy changes of the hydrogen atom are attributed to the electron transitioning between energy levels. However, the energy itself is that of the whole system (proton+electron) so how can we attribute its changes to the electron? what's preventing us from attributing these chan...

It is known that Einstein was impressed with the elegance of Maxwell’s Equations for electromagnetism, and that he was striving for something similar for gravity in his General Theory of Relativity.

In TikZ one can specify a node by a command like \path (0,0) node[node contents=A]; This is very useful if one wishes to apply a command to the text in the node, say, to avoid writing \node at (0,0) {\contour{red}{A}}; and simply set \path (0,0) node[node contents={\contour{red}{A}}]; (which c...

When I looked at my profile and Steam purchase history, it was empty. I don't know how to recover the games and money I had...

I recently bought a second-hand Yamaha P-45 to replace my old Yamaha PSR-F51. But when I tried it, it feels heavy, and the keys are strong; I feel like I don't know how to play the piano. Is that normal? the keys are that strong compare to my older one? I never played on a grand piano so I don't ...

I want to know the numbers needed to build a capacitor bank to sustain a load of 36 V, 1500 W up to 5 - 10 minutes at time before needing recharge. I have four 10,000 μF, 40 V caps connected in parallel to a 12 - 36 V booster with a 36 V, 1500 W load connect to the other end of the cap bank. Ok,...

Code for Master #include <Wire.h> void setup() { Wire.begin(); Serial.begin(9600); } void loop() { Wire.beginTransmission(9); Wire.write('c'); Serial.println('c'); Wire.write('a'); Serial.println('a'); Wire.endTransm...

Let's assume I am playing my character in Pathfinder 2 and am attempting to stab my foe. This foe is clumsy 3 (because of a spell my friend casted earlier) and I somehow also have it flat-footed. As far as I know being clumsy gives a status penalty to AC, as does being flat-footed, and those two ...

I learnt this week that if we divide an octave into 53 notes (53-TET), then all basic intervals approximations will be improved. I am trying to understand how one would play a normal song (for 12-TET) given an n-TET instrument. Suppose I came across a hypothetical n-TET keyboard, which has keys l...

I have a lowpass filter with the transfer function \$H(s) = -\frac{3}{3s^2+s+3} \$. Converting it to standard form yields $$H(s) = -\frac{1}{s^2+\frac{1}{3}s+1} $$ Comparing this to the standard equation \$\frac{\omega_n^2}{s^2+2\zeta\omega_n+\omega_n^2} \$ we see that \$\omega_n = 1 \text{rad/s}...

Is there a way in D&D 5e to force a creature to reroll a saving throw they just succeeded on? I know there are lots of ways to impose disadvantage or other penalties, but I’m specifically looking to make them reroll a successful saving throw. My DM is always very smart with what they do/don’t use...

In Vulgate, Matthaeus 4:23, it says "et prædicans Evangelium regni". Shouldn't it be "regno" (dative) rather than "regni" (genitive)? He was talking the gospel TO the kingdom, not the gospel OF the kingdom.
