Boy, Do We Have Threads On The Double-Slit

  • Thread starter ZapperZ
  • Start date
In summary, there have been numerous threads on the double-slit experiment in the Physics Forums, with over 30 alone in 2016 and 2017. This topic is one of the most commonly asked about, with some members suggesting the creation of a dedicated section for the double-slit. There have also been recurring questions and discussions about the mysterious nature of the experiment, with some suggesting the need for an FAQ or a new "double-slit" t-shirt. However, there have also been concerns about the repetitive nature of these threads and the possibility of multiple accounts being created to ask the same questions. To address these issues, it is recommended that the first paper linked in this conversation be read

PF Mentors: I'm not sure where this should go, so feel free to move it to a more appropriate forum.

I was waiting for one of my students to finish editing a couple of his graphs and figures, and I got bored. So as often the case, I browse PF (hey, what else do you do when you get bored?). I noticed another thread on the double slit, and just out of curiosity, I decided to do a quick search on the Quantum Physics forum on threads that we have had related to the double-slit. I knew that we have had a lot, but even I was shocked at how many and how often such a question/thread has appeared.

I don't have a good reason for compiling this (maybe someone might be able to use it to look up something?). I also did not include every single thread that I found. I did not include the ones that started off already in La La Land (with apologies to the excellent movie). I also did not include the ones that were started by members that have... shall we say, departed from the forum. I limited this list only to those created in 2016 and 2017.

So in effect, there are many more threads on the double-slit than what I listed here, which is astounding.

I will not be surprised if this is the most-asked topic on PF.

Zz.
I counted 30 in your list.

It is probably because so many popular accounts stress the spurious mystery of 'which path information'.

Looks like we need a double-slit FAQ. (Or do we already have one?)

If you take the homework forums into consideration we have some topics that have been asked hundreds (possible a few thousands) of times.

I think you've shown a new "double slit" tee shirt would be a seller.

Another common topic is definitely "Expanding Universe." 100 threads came up from my thread search for it :wideeyed:

I have noticed the same kind of questions popping up in the QM forum about the double-slit, to the point that I think its someone creating numerous accounts to ask the questions. Though I am probably wrong on that.

We need a big sign above the QM section, or an automatically inserted image / video saying:

Double-slit closed! We fixed it! Eventually lost photons and electrons can be picked up in the Schrödinger ball park at Calculus.

This list can be linked in future double-slit threads.

Hmm. Can we implement something like the following:
I search for a topic, if there are matches in Insights they are top of the list. Period. No exceptions. If a FAQ exists, it gets second billing only to Insights.

We may have this, partially, but I have yet to see it happen. Try a search for 'secant' - Stevendaryl's insight shows up in 3rd position. If you want to follow @bhobba's suggestion in combination with @Greg Bernhardt push for insights, this change creates a valid driver. For both predicating the reading a paper first (or a summary) and increasing the usefulness of Insights. win/win.

Technically FAQs are Insights. This could be managed by weighting the Insight prefix. However how to rank when there are multiple Insights in the search result feels tricky.

Insights and FAQ's are clearly seldom the first choice of new posters. Zz's first post is proof positive. PF is a really good source of information. IMO, accessing what @bhobba and a lot of other people indicate, does require some kind of change. That's why you get the big bucks for implementation :biggrin: And a key to the men's room.

Part of it is making the useful information more accessible, but human nature will always gravitate to what is easiest and what is easiest is always signing up and posting without any kind of effort to read or find the information yourself.

Would you be more interested in writing an Insight if this feature is added?

I always thought the useful information was easily accessible ?

Although, a person can't make a post unless they are a member ...

@Greg Bernhardt - Have had one written for along time now - on very basic calendric programming - calendars, the use of epoch dates, etc. And no, that's not a factor.

Submit it! :)

btw, working on the search feature!

Ok the best I could do is put an Insight to the top of the search result for whatever page it ends up in for those results. So if it ends up on page 1 it's at the top of page 1, page 2 it's at the top of page 2. I couldn't get all Insights at the top of page 1. It's an improvement, but not the best.

Okay, I'll buy that. Thanks for your help.
 

1. What is the double-slit experiment?

The double-slit experiment is a famous physics experiment that demonstrates the wave-particle duality of light and matter. It involves shining a beam of particles or waves through two parallel slits and observing the interference pattern that is formed on a screen behind the slits.

2. Who conducted the double-slit experiment?

The double-slit experiment was first conducted by Thomas Young in 1801, but was later refined and popularized by other scientists, including Augustin-Jean Fresnel and Albert Einstein.

3. Why is the double-slit experiment significant?

The double-slit experiment is significant because it helped to shape our understanding of the behavior of light and matter. It showed that light and matter can exhibit both wave-like and particle-like properties, which was a revolutionary concept in physics.

4. What is the connection between the double-slit experiment and quantum mechanics?

The double-slit experiment is often used to explain the principles of quantum mechanics, specifically the concept of superposition and the role of the observer in determining the outcome of an experiment. It has also been used to support the idea of parallel universes in the multiverse theory.

5. How has the double-slit experiment been applied in other fields?

The principles of the double-slit experiment have been applied in various fields, including optics, electronics, and even psychology. It has also been used in technological advancements, such as the development of electron microscopes and quantum computers.
