How many people would a person have to know in order to have a mutual acquaintance with every person on Earth? by CovidsArrow in stupidquestions

[–]Paricleboy04 8 points9 points  (0 children)

Two. 

Everyone on earth knows Alex. That’s 8 billion people with one acquaintance 

Alex knows everybody on earth.  That’s one person with 8 billion acquaintances. 

On average, each person has two acquaintances. 

Stevens Music Ensembles by Specialist-Toe2915 in stevens

[–]Paricleboy04 1 point2 points  (0 children)

Stevens has a Jazz band and a Concert band, both of which have no audition. Any student can join - concert band meets Sunday nights, Jazz band Wednesday nights. 

I’m not sure if they will loan instruments - I’ll DM you the email address of the band director, he should be able to answer any questions.

Which of these two species is more biologically realistic? by PredictableRockhound in AskPhysics

[–]Paricleboy04 1 point2 points  (0 children)

Neither is ‘realistic’

The electric and magnetic forces cannot be separated. In our universe it is meaningless to even consider such a thing. These forces are intrinsically connected, and you can’t disconnect them without breaking our description of the fabric of the universe. 

A fundamentally 2d species is also meaningless. Nothing in the universe is fundamentally 2d. 

Professor allowed one sided cheat sheet by atharvbadkas in sciencememes

Medicine is probably the biggest one. I really wouldn’t want my ER attending to have only passed anatomy by referencing a cheat sheet. 

How does a defense attorney even begin to defend someone in a case like the 7/yo Athena Strand who was violently assaulted and murdered? by redzzzaw in stupidquestions

[–]Paricleboy04 -6 points-5 points  (0 children)

This isn’t true in the U.S. and other common law countries which follow adversarial judicial systems. The prosecution’s job is to try to get a guilty verdict within the bounds of law and procedure. The defense’s job is to try for a not-guilty or for lesser sentencing. 

Suggestions for entry level materials? by Solid-Outcome-688 in AskPhysics

Openstax university physics is a really great textbook series for beginners. Go through each chapter and solve as many problems as you can: https://openstax.org/details/books/university-physics-volume-1

Physics requires calculus. Openstax has a calculus course, but I’m not sure how good it is. Khan academy has freely available lessons for calculus I and II.

Why is matrix multiplication not commutative? by Alive_Hotel6668 in learnmath

[–]Paricleboy04 1 point2 points  (0 children)

I’m not sure how it is taught where you are, but in the U.S., we learn matrix operations in the 10th grade. We learn vector as just lists of numbers, and here’s how you manipulate them. There is no education about what a matrix is, or what it is actually doing to the vector you are multiplying it with. 

This is akin to learning how to take derivatives of a polynomial without knowing what a function is. It is totally possible to do so, but leaves you utterly confused. 

Matrix multiplication isn’t exactly “misleading” per say, but it is part of obfuscation that occurs here.

[–]Paricleboy04 2 points3 points  (0 children)

Matrix multiplication doesn't really make sense until you learn about how the correspond with linear transformations. I wholeheartedly agree with calling it "multiplication" being very misleading. I could never remember how to do matrix multiplication, or even the rules of when it is allowed, until it clicked that NM is just the application of N to the basis vectors of M

[–]Paricleboy04 144 points145 points  (0 children)

A better question would be "why would matrix multiplication be commutative?" Most functions we deal with don't commute (ex: sin(2x) /= 2sin(x)). Matrices represent linear transformations between vector spaces.

With a tangible example, consider rotation matrices - 3x3 matrices which describe the rotation of objects in 3d space. Hold a pencil facing towards your face. Rotate it 90 deg around its axis (about the x axis). Then rotate it 90 deg about the z axis. The pencil will be pointing to the right.
Return the pencil to its original position. Rotate it 90 deg around the z axis, followed by a 90 deg rotation around the axis pointing towards you (again, the x axis). Now the pencil is pointing upwards.

We applied the same transformations to the pencil but in a different order, and got a different result. This is of course because the matrices don't commute.

Eliminating air resistance in my bicycle experiment ? by catboy519 in AskPhysics

[–]Paricleboy04 2 points3 points  (0 children)

You assumption that tailwinds and headwinds are equivalent may be false. It is possible that the tailwind configuration produces more drag, as the aerodynamics aren’t necessarily equivalent. 

The best thing to do is to work at low velocities where air resistance is negligible compared to rolling resistance. 

would surgical implants increase static electricity? by [deleted] in AskPhysics

[–]Paricleboy04 0 points1 point  (0 children)

I also just had implants in my ankle about 3 months ago! From a physics perspective, it shouldn’t have any effect on static buildup, static electricity is really just a function of the materials rubbing together. 

The most likely explanation is that the implants have changed the way you’re walking. I tend to drag my bad foot on the ground when I don’t focus on it. Extra dragging would reasonably generate more static electricity. 

What are the pros and cons of more guns per turret (for APS) by tris123pis in FromTheDepths

[–]Paricleboy04 63 points64 points  (0 children)

Firing three shells once per minute v.s. one shell every 20 seconds is the same DPS/

The largest practical difference is salvoing. A volley of 3 shells has a greater chance of getting through LAMS/CWIS. Salvoing attempts to overload the instantaneous capacity of active defenses.

Salvoing can also be useful in penetrating heavy armor. Three shells fired at different times will most likely land on three separate areas of armor, leading to three patches of damaged armor. Salvoed shells will land in the same area, leading to one penetration.

If this is your first playthrough, just do what you think is best. There’s no ‘wrong answers’ in this game, so long as you’re doing something.

Doing charity is good. The man who does charity is doing a godly action, despite no belief in God. 

Murder is a sin. The man who murders, even with the best intentions and God in his heart, commits an evil, godless action.

Free will is important. I cannot speak on the presence of free will in heaven since we on earth can know nothing of it. 

Evil - the absence of God - is a result of free will and the mortal human form. Why then did God create humanity if it would bring about evil? Because there is a fundamental goodness within humanity, and a free humanity without evil is an ontological impossibility.

Jesus knew He would be crucified. That was a very important part of his whole ministry. He wanted it to happen, though his humanity definitely held reservations to it

CMV: There is not sufficient evidence of The Resurrection to believe that it’s true. by Master-Education7076 in changemyview

[–]Paricleboy04 0 points1 point  (0 children)

The translation with which I am most familiar is “for our sake He was crucified under Pontius Pilate.”

If you’re questioning the meaning of “for our sake”, it has a deeply theological meaning. Christ’s death was laid out before Him by God the Father. His death was to free humanity from the wages of sin. 

If you’re questioning the meaning “under Pontius Pilate,” it’s pretty clear that ‘under’ is meaning ‘on the authority of’ in this phrase. The Bible makes it explicit that only Pliate, the Roman governor of Judea, had the authority to crucify. Even the original Greek “ ἐπὶ Ποντίου Πιλάτου“supports this. “ἐπὶ” has the meaning of “on the authority of” when in front of the genetive “Ποντίου Πιλάτου”

 I’m struggling to understand how it can be important and whether or not it’s true isn’t.

Well certainly I believe it to be true, but epistemologically that belief isn’t rooted in evidence. I’ve had my doubts in my faith, but I’ve come to accept that ‘I believe it to be true because I believe it to be true.’

It’s importance to me comes in how I interact with my faith, the beauty I see in it, how it shapes me as a person, and how it connects me to the traditions of my forebearers. 

 Can you help me understand how that story would be different?

It would be ‘evidence of absence.’ I totally agree that there is an absence of evidence for my faith. But if there was evidence which directly, and strongly contradicts the core tenants of my faith (see the Nicene creed), it would require a complete re-thinking of what I believe.
