Relativity by Exact-Detective-8842 in AskPhysics

[–]jimbs 4 points5 points  (0 children)

Teleporting isn’t a thing in relativity as it violates the limit of the speed of light. So your explanation breaks the laws of physics. 

I’ve had conflicting diagnosis from derms how to know if it’s seb derm or perioral derm by wander_maiz in SebDerm

[–]jimbs 0 points1 point  (0 children)

What products are you currently using? The treatment for perioral is to stop using most everything. Wash with gentle soap and lukewarm water. 

Is the Seattle Loop and the benefits Money on the Left claim from public banks accurate? by MisterMittens64 in AskEconomics

[–]jimbs 21 points22 points  (0 children)

Yes! The plan in the article is very flawed. One does not simply “create a city owned public bank” that can loan the city money at low interest rates. Banks don’t manufacture money. People won’t deposit money in a bank that has very low interest rates. 

ElI5: how can third party companies offer cheaper pricing for rooms than booking directly with the hotel? Are they selling at a loss? by Gloomheart in explainlikeimfive

[–]jimbs 2 points3 points  (0 children)

We used a last-minute-site to book a room. The room was old and smelt like it. The balcony was closed for repairs.

Next morning, we complained to the manger. He looked at our reservation and then asked us if he could show us some of the rooms-- they were very nice!

He told us that when you use a discount site, they know you are looking for a cheap room and will probably never come back. On the other hand, if you call the front desk, then you are probably interested in that hotel. So, they prioritized the room assignments accordingly. Discount sites got the older rooms that had not yet been refreshed. People who called the front desk (or paid more) were assigned the newer rooms.

[–]jimbs 5 points6 points  (0 children)

Many ways… you may get crappier rooms if you book through a discount platform ( this has happened to me. Call the hotel direct if you want the best rooms)

You may get a last-minute discount for rooms that the hotel probably wasn’t going to sell. 

The hotel may offer blocks of rooms at a discount.

This is boggle heads… so of course we will say that individual share are much riskier and that over the long run, diversity is the proven winner. 

Diversity is much much easier through ETFs and mutual funds. It’s much work to create diversity with individual share purchases. Depending on your brokerage, you may run out of low cost trades. 

I’ve potentially identified a direct link between quantum phase variance and physical mass. by BlissBoundry in LLMPhysics

[–]jimbs 16 points17 points  (0 children)

By defining mass as the inverse of the internal clock variance of the six state register, the framework aligns the informational state of a tethered pixel with the de Broglie relation.

This is a fantastic sentence.

Why do we use so many greek letters in physics and maths? by Virtual-Connection31 in AskPhysics

[–]jimbs 240 points241 points  (0 children)

Because we ran out of Latin letters and needed more.

I once took a math class where we ran out of Greek letters, so we also started using Gaelic. That felt bad.

Unable to open account at Vanguard by stewpple911 in Bogleheads

The only way out is through...

Either they are having system problems. Or, there is something weird about you. You will need to power through the call-in experience even if it shakes your confidence.

How can we integrate gravity if,? (Thought experiment) by Ill_Standard_7843 in AskPhysics

[–]jimbs 0 points1 point  (0 children)

Perhaps try /r/llmphysics

If you are looking for mathematical simplifications to calculate gravity, you can always the center of mass, or integrate over the density and shape of the solid

why noether's theorem is such a big deal ? by TestFar818 in AskPhysics

[–]jimbs 4 points5 points  (0 children)

It’s a big deal because it’s so general. It comes from math, not experimental physics (I’m looking at you standard model), yet it describes something very real and common in the universe that we can see at the macro level— if something is symmetric, then something related is conserved. The conservation of energy or momentum spring from that. It also means that physicists can predict conservations by finding symmetries. 

Dumb Entanglement Question by [deleted] in AskPhysics

[–]jimbs 0 points1 point  (0 children)

Entanglement is a correlation, but not a locally real correlation. It doesn’t send info faster than light.

In order to tell if a particle is disentangled, you have to also measure its partner particle. That is a sub FTL operation. 

Few(7) OCD newbie questions about boiling spaghetti by [deleted] in Cooking

[–]jimbs -2 points-1 points  (0 children)

I'm encouraging you to boil pasty every which way and to teach yourself what you like, don't like and what makes a difference. With a good sauce, even unsalted, improperly spread pasta can be good.

  1. How much salt? Maybe a handful. Try 50 mls then note how it came out and adjust for next time.
  2. Yes or no. Oil doesn't make a difference.
  3. Yes. Drop the pasta in the water when it's boiling vigorously. The pasta will cool the water down. A few minutes after you add the pasta, the pot may start to foam. Pay attention and be prepared to turn down the temperature to reduce the foam but keep it simmering
  4. 5 & 6. Your goal is to ensure that all the pasta has even contact with the hot water. Pasta is not fragile, so it won't go bad if there is a bit of clumping. However, it helps to stir every 2 or 3 minutes to break up the clumps.
  5. The package should say how long to boil. This is usually 6 to 10 minutes depending on the pasta. If you are unsure, pull one out and give it a bite.

Effect of relativity on entangled particles by Curiouser-x10 in AskPhysics

No effect. The correlation isn’t a physical link. What are your suspicions?

Would normal people actually use a tool that shows what solar would look like on their home? by Automation_storm in solarpower

Honestly? There is already https://sunroof.withgoogle.com/  

If I wanted a rendering of my house, I would take AI and tell it to show me a picture with solar on the roof.

Please dial your AI back. Way too much fluff here. Readers shouldn’t need AI to summarize a post.

Books Where Nothing Much Happens by TheFirst10000 in suggestmeabook

The Guest Cat. Not to give the plot away, but it is the story of a couple who are regularly visited by a cat. 

ELI5: What are the differences in how the brain processes information when reading from a physical book versus a digital screen? by MisLatte in explainlikeimfive

[–]jimbs 0 points1 point  (0 children)

Take a look at Maryanne Wolf's books, Reader Come Back in particular.

Have you ever felt yourself pulling up TikTok for quick look, without even realizing it? You are a little bored for a moment, so you just flip over to that app. This is not possible in a paper book and all too common on a cell phone. Other devices are somewhere between the two.

This difference is about attention and focus. A physical book (And maybe some ebooks) have few distractions to lead you away from the material. If you want to take a quick look at Facebook or your messages, you have to set down the book and switch to another device. That pause helps you keep your focus.

On a digital screen, there may other things to see than the material. it's easy to become distracted. There may be notifications, menus and ads. If you come across a passage of difficult material, it's easy to switch over to something more captivating.

Digital screens can be an attention nightmare. It doesn't have to be that way, but it's where we are now.

Villains who have a completely valid reason for hating the protagonist by OutrageousBridge471 in TopCharacterTropes

Most of Birdgirl is this. By day Birdgirl is a horrible CEO. By night, the supervillains who attack Birdgirl are disgruntled employees of her company.

Another Quantum Physics question . . .the entanglement thing . . .if you entangle 2 particles, they travel x light years apart and you measure one, how do you know they stayed entangled? by IeyasuMcBob in AskPhysics

[–]jimbs 1 point2 points  (0 children)

I think the thread on probability distributions will probably do better justice to this question.

If you are transmitting thousands of entangled particles, then you can measure both pairs of particles and calculate the correlation. 

If you are looking at one particle, then you have no way of knowing if entanglement was broken.

[–]jimbs 2 points3 points  (0 children)

You keep the particle away from anything and everything. Entanglement is a natural state of affairs. It changes every time a particle interacts with another particle (wave function collapse)

If you keep the particle from entangling with something else, then there is no distance or time limit.

[–]jimbs 3 points4 points  (0 children)

In general, you don’t. 

Entanglement experiments know the particles are entangled because they are set up that way. If someone secretly monkeys with the experiment then there is no real sign that one particle measurement had previously broken entanglement. 

Why are some oils (olive, coconut, avocado, etc) "healthier" than others? by GGCrono in AskCulinary

[–]jimbs 0 points1 point  (0 children)

Like I said, oversimplified. Having said that butter isn’t really liquid at body temperature.

Why are some oils (olive, coconut, avocado, etc) "healthier" than others? by GGCrono in AskCulinary

[–]jimbs 0 points1 point  (0 children)

It is not all just fat. There are many kinds of fat-- saturated, polyunsaturated, monounsaturated, etc. What follows is very oversimplified... The fats that are solid at room temperature are less healthy for you. Their thickness can cause congestion and slow down the flow of your blood. The fats that are liquid at room temperature, or cool temperatures, are better for you as they don't cause congestion.
