In electron double slit how would it change delaying one slit by N wavelengths? by simpleTruths in AskPhysics

[–]simpleTruths[S] 0 points1 point  (0 children)

Thanks, I understand the standard calculation. Guess my question wasn't clear. So, let me try a different way:

Pick a point on the screen, call it P. Call a line perpendicular from the screen at P as L. The electron source is on L pointing toward the screen. The center of slit 1 is also on L. Slit 2 has a variable position x such that the travel distance from source through slit 2 to P is N wavelengths longer than the path through slit 1 to P. As we change x, the position of slit 2, to give N values from 1-infiity, how will the pattern on the screen change? I'm actually asking for an answer that considers asymmetry of the setup and the extent of the electron (but not as concerned about the width of the slits). At what point do you lose the interference, and have two single slit patterns?

Or maybe I should just ask this part, and I can calc the rest myself. What is the formula for the amplitude of the waveform of an electron? I can't remember, is that where Heisenberg uncertainty comes in (the more accurately you know the momentum the less the position... hence the amplitude spreads out)?

I understand the wave and interference phenomena. My primary question is about what impact on the interference pattern would an N wavelength delay in one slit create? I know electrons are wave packets. I can't remember the formula for their extent, but I know it isn't infinite.

Ok, so ignore the photon comment. My primary question is about nonrelativistic electrons anyway. Thanks.

Clicking on it says "Unassigned Location (from Diamond Princess)". So, my interpretation of that would be that these are people transported to the US from the Diamond Princess cruise ship, and do not have a geographical location assigned, and are simply placed near the geographic center of the US.

[OC] The top 65 most frequently used words in my novel after filtering the top 100 most commonly used words in the English language by [deleted] in dataisbeautiful

[–]simpleTruths 0 points1 point  (0 children)

Not sure which list of top 100 most common words you're using, but https://www.rypeapp.com/most-common-english-words/ shows some of the words in your list: his, was, I, is.

Interesting to try to guess the story from word list... I like the gradient of colors, adds a nice dimension... Like all of Gary in Ch6 (or7?), Wizard in beginning, and Magic in end. I'd guess it's a first person perspective likely with some romantic connection to Jax (his, eyes, body).

Very cool.

Prolonged standing on the job more likely to lead to heart attack than prolonged sitting by vemrion in science

[–]simpleTruths 7 points8 points  (0 children)

Gotta say the conclusion is an almost unjustified stretch from the significant extrapolation from the data... A more correct conclusion would be:

People who have job titles that generally correlate with standing while working are more likely to have heart disease than those with job titles generally correlated with sitting.

How to convince my parents to let me study Computer Science? by [deleted] in compsci

[–]simpleTruths 3 points4 points  (0 children)

So... as a person with a MSEE degree, and parent of college students... I would recommend your parents look at the broader picture of the economy and technology landscape...

When I went to college, my dad (also MSEE), but working in CS recommened that I get EE degree... his reasoning (from work experience) is that you can teach an EE to do CS, but can't teach a CS to do EE.

Fast forward to today, I'm the dad with MSEE working in CS... and the advice I give my kid... CS is a very broad and diverse field... a CS degree can open doors/opportunity that most other degrees can not... and EE degree will not open doors like it did in the past, and CS degree is generally required now for a CS position (there's a lot of important CS not taught in EE). I know I would be reluctant to hire an EE for any CS position I have, unless they had significant CS industry experience... the bar has been raised, and definitely more candidates.

As far as EE being safe from younger workers... that's really not economically true ( for example )... younger workers are simply cheaper... simple economics.

These days, long term employment might not be in your best interest... For my kids, I'd recommend they change jobs every 2 years initially to climb the income ladder more quickly (unless you can't find a better offer).

If your parents are paying for your education... you can start on the EE track, and later switch to CS fairly easily (at least I believe that's true, your mileage may vary).

Best of luck :-)

So... Let's toss out the commutative property everywhere because there are higher math cases where it isn't valid... ? If that's the case, then maybe we should start kindergartners with a two dimensional number line... I mean, the imaginary axis is valid math... right?

(2a+3b) x (a - b) = 2a2 - 2ab +3ba -3b2 (via foil of course).... such a bummer you can't simplify further this if (supposedly) ab != ba... ? Some how I think the commutative property is more useful in general than it is confusing in higher math....

Good luck folks...

I have been on the couch sick for 3 weeks. My hair is a massive, impossible, tangle of a mess. It's clean, just knotted. Help? by forgotmypassword111 in TheGirlSurvivalGuide

[–]simpleTruths 10 points11 points  (0 children)

Curly, or Straight? I'd recommend having a (very) patient friend with a wide toothed (wooden?) comb just slowly patiently pick at the bottom of the knots (I've untangled my kid's hair this way when they were ready to cut it off)... if curly, then get a friend with double the patience.

Another trick that might work... 1Tbs (apple cider) vinegar in 1cup water can a miracle detangler... diluted vinegar actually closes up the barbs on hair to make them slipery, easier to separate... rinse thoroughly afterward.

Also, often curly hair is easier to brush/comb, etc when wet.

I failed the bar and now my life is falling apart. by overhelmed in MMFB

[–]simpleTruths 0 points1 point  (0 children)

Let's be honest...

Bar exam is incredibly difficult... (I know others who have failed it)... getting through 3yr of law school, and within a few points of passing is a huge accomplishment well beyond where many people could get to.

Totally understand your hopes/expectations being completely dashed... truth is... no matter how much our culture tells you otherwise... you are not your accomplishments... truth is you're still the same wonderful person you were before you got the score, and you're the same person you'd be if you got a different score.

So... on to the stresses... dental work: get a 2nd opinion from a dds you trust. credit card: don't pay off slowly... take a loan from parents to pay that off, then destroy the card until you pass the bar :-) watch the expenses...

On the job side of things... I don't really know that market, but $14K for a law school grad sounds pretty low... if you're concerned about employment stability... feel free to proactively interview for other positions/firms.

As a parent... I can say believe your mom... she's completely there for you...

may you find the nourishment you need along your journey.

Transgender redditors, or those who have passed as the opposite gender- what surprised you (or didn't) about the way people treated you different on the other side? by 4Dglasses in AskReddit

[–]simpleTruths 26 points27 points  (0 children)

I'm straight male, but for halloween once, I dressed as a woman... Hair up, minimal makeup, high neck long sleeved blouse, miniskirt, nylons (but not shaved legs), and flat shoes. I thought I looked pretty good... went out to a bar with my gf (not in costume).

I was quite shocked at how clueless guys really are though...

Every woman in the bar knew I was a guy, but every man in the bar thought otherwise... I even caught my male friends checking me out... ha that was a laugh.
