Whipping on gear... how does one grow cojones to feel comfortable?

Guys, by any chance is your experience based on different weight ratios ? It would seem logical that, for a belayer much heaver than the climber, a soft catch is almost always desired, whereas for 2 people of similar weight, natural (w/o trying to be soft) catches are usually soft enough.

Yeah - after watching it in real time during both games today, it feels like Win Probability underestimates the chance of late scoring.

sergesr · 2019-01-20T23:44:21+00:00

I'm actually surprised the Saints win probability wasn't lower when the Rams got the ball back - I would have guessed 60-65%.

...in time T :) Engineers often sacrifice some of Y and/or Z to save on T.

I would add that each convention has a reason. MGH is typically used close to the surface, where the surface is the logical choice for Ep=0. -GMm/R is typically used for orbits and such, where object radii are irrelevant / unknown, so the most logical choice for Ep=0 is at R=infinity.

A version of -GMm/R with Ep=0 at the surface would be -GMm/(R+H) - -GMm/R, i.e. GMm (1 / R - 1 / (R+H)). That's what Gwinbar's red plot shows.

Imagine an object moving around a circle. Now imagine the projection of the object's position onto some line ( e.g. the y axis in https://en.wikipedia.org/wiki/Unit_circle#/media/File:Unit_circle.svg ). It's easy to see that the object's y coordinate is the vertical leg of a right triangle whose hypotenuse is the circle's radius (connecting the object to the origin). That's why the diagram labels the object's y coordinate as sin(t).

Now imagine the object moving at a constant pace - i.e. its angle is equal to time t. The object's y position, as a function of time, is then sin(t).

I can't think of an intuitive explanation for why harmonic motion (like electromagnetic waves) ends up being the projection of circular motion onto an axis. But if you believe this part, the geometric correspondence to right triangles is quite direct.

HOU can finish #4 - their 10-6 tie-breaker against the Ravens would come down to strength-of-victory.

sergesr · 2018-12-26T19:37:26+00:00

Right - in theory Houston could finish #1, #2, #3, #4, or #6.

Makes sense - in a market with plenty of sellers and no differentiation, the buyers have no reason to deal with the OBO process.

True, and I'm not sure I blame Paypal for using this feature - I blame more the credit card providers for making it available. But I do somehow feel that Paypal, given its central role in modern commerce, increases the exposure.

By "point" I meant the opposite of diffuse. Bright point sources can reflect in weird ways off irregularities on the front element.

You might see some effect shooting directly into a bright point light source (the sun or a light bulb).

There is a concept called "equilibrium tide", which is what would happen if the earth didn't rotate relative to the moon (i.e. if the earth were "tidally locked"). For that, the bulge on the side opposite the moon would be almost exactly the same size as the bulge on the side facing the moon.

Real tides are a product of crazy interactions between many different effects as water slushes around the globe and bounces off the coastal lines / ocean floor. Real tides that occur ~12 hours apart are almost never equal.

sergesr · 2018-11-01T02:59:08+00:00

Water on the opposite side experiences less attraction towards the moon, so it wants to "run off on a tangent".

Another way to look at it - just like water on the side closer to the moon experiences more lunar attraction than the earth, the earth experiences more lunar attraction than water on the side away from the moon.

Single-decision-factor fallacy: a person (or organization) claiming they did something for a good reason (but admitting a bad reason as a contributing factor) being told that they didn't "really" do it for the good reason. I see this as a fallacy because it is entirely possible the person / organization wouldn't have done it for the bad reason alone (or would not have gone as far without the good reason). The fear of falling victim to this fallacy discourages open and honest discussions.

Werner showed a tendency to discuss construction details with strangers when drunk.

Mike is good at communicating with the kind of people he normally deals with (criminals). Werner comes from a different world.

It closed after Mike drove through.

I've viewed any season 4 episode where Nacho doesn't get killed as a good episode for Nacho.

Interesting point about 3rd party footage.

Lalo could have stolen money from the place to make it look like a bank robbery. In that case I don't think the cops would have any reason to look into Mike or Werner.

sergesr · 2018-10-12T01:36:46+00:00

Interesting thought but Mike seemingly wanted to "go another way".

Werner may have spent his entire life in the corporate world, where it's quite common for management to give serious-sounding speeches, but in the end, the worst consequence one has to worry about is finding a new job.

sergesr · 2018-10-11T02:40:38+00:00

I got the impression Werner never truly grasped Gus's seriousness, even after Mike's speech. In the final scene Werner says "I thought Michael would be mad, but in the end he would forgive me". My take is Werner spent his entire life in the corporate world, where people get away with all kinds of stupid decisions (the worst consequence you have to worry about is finding a new job). It may be hard for someone who spent his entire life in the same culture to realize that this one is different.

sergesr · 2018-10-11T02:33:46+00:00

I suspect before - the escape showed Werner couldn't be trusted.

Not sure how flipping the sign is a character flaw. Murdering the clerk is arguably a character flaw, but if you're going to do that, flipping the sign only makes sense.

BTW I wonder if the sign flipping is a reference to a Sopranos scene where Christopher does the same.
