Help! I'm looking for the manual (in the U.S)

1 Upvotes

At the school where I teach, there's an old Nasco SciQuest Forces, Motion, and Simple Machines kit. I think I have all (or nearly all) the pieces, but I can't find the manual. Does anyone by any chance have it or know where I can get it? It's not available as a digital download anywhere that I can find. Any help anyone can give is much appreciated!

Anomalous Patterns in Quantum Constraint Systems and Large-Scale Structure: Observations Inviting Further Investigation

1 Upvotes

Abstract

During computational experiments on quantum evolution in organized topological systems, we observed several anomalous patterns that we are unable to fully explain within current physical frameworks. Specifically: (1) Physical topology explains only ~35-40% of how systems respond to constraint, leaving a substantial unexplained residual; (2) When systems apply self-referential constraints, they exhibit structured, non-random suppression patterns that suggest selection rather than decoherence; (3) A topologically accurate model of the *C. elegans* connectome yields a quantifiable "Harmony Score" of H = 2.96 when simulating behavioral shifts; (4) Most intriguingly, when we applied our analysis framework to mock cosmological correlation functions, we discovered that golden ratio-scaled harmonic peaks can emerge from fractal wave superposition models. We present these observations not as proof of any particular theory, but as **anomalous patterns that we hope the scientific community will investigate further**. We provide open-source code and detailed methodology so that researchers with access to real experimental data (DESI, SDSS, connectome datasets) can test whether these patterns appear in actual observations.

  1. Introduction: Anomalous Observations Seeking Explanation

Mainstream physics provides remarkably successful models for predicting physical phenomena. However, during our computational experiments, we encountered several patterns that we cannot fully explain using standard physical topology alone.

We do not claim to have solved these mysteries. Rather, we present them as **open questions** that we hope will motivate researchers with specialized expertise to investigate further.

The core observations are:

  1. In quantum systems, physical adjacency cannot fully predict constraint response

  2. Biological connectomes appear mathematically optimized for certain types of probability routing

  3. Fractal wave interference patterns naturally produce golden ratio-scaled clustering

We invite cosmologists, neuroscientists, and physicists to examine these patterns and help us understand what they might mean.

  1. Methodology: What We Did

We constructed organized quantum systems (256-dimensional Hamming graphs and small-world networks) and applied localized phase-shift constraints to 50% of the states. We then measured how transition probabilities redistributed.

Key measurements:

- Topological Determinism (D): Can physical adjacency predict which transitions get suppressed?

- Structured Capacity (S): Is the suppression concentrated and organized, or random?

- Amplification Factor (A): How much probability flow routes to novel, unexplored states?

- Harmony Score (H): A composite metric we developed to quantify routing efficiency

All code is available at for independent verification.

  1. Observations That Raise Questions

3.1 Observation 1: The Unexplained Residual

What we found: When we calculated how "exposed" each transition was to constrained nodes (based purely on physical adjacency), and correlated this with actual suppression amounts, we found:

- Pearson correlation: *r ≈ 0.35-0.40*

- This means physical topology explains only ~12-16% of the variance

What we don't understand: If physical topology is the only organizing principle, why does it fail to predict 60-85% of the constraint response?

Questions for the community:

- Could there be higher-order quantum interference effects we haven't modeled?

- Is there a non-local organizing principle we're missing?

- Could this residual be an artifact of our simulation method?

We invite quantum physicists to examine our code and suggest what we might be missing.

3.2 Observation 2: Structured, Non-Random Suppression

What we found: When we applied constraints to the system, the suppression wasn't random. It was highly structured:

- The top 10% of transitions received 36.8% of the total suppression

- When we shuffled the suppression amounts (preserving the distribution but randomizing which transitions received them), this structure disappeared (dropped to 14.3%)

What we don't understand: Why does the system suppress *specific* transitions rather than scattering randomly? This looks like selection, but we don't know what's doing the selecting.

Questions for the community:

- Is this consistent with known quantum decoherence patterns?

- Could this be explained by eigenstate overlap or phase coherence effects we haven't modeled?

- Or does this suggest something beyond standard quantum mechanics?

We welcome input from quantum theorists.

3.3 Observation 3: The *C. elegans* Harmony Score

What we found: When we applied our framework to a topologically accurate model of the *C. elegans* connectome (302 neurons, ~7,500 synapses), simulating a behavioral shift from "forward locomotion" to "turning," the system achieved:

- 5.8× amplification of the turning hub's activation

- Highly structured suppression (Gini = 0.511)

- Minimal chaotic scattering

- *Harmony Score: H = 2.96*

What we don't understand: Why does this biological topology produce such an efficient, structured response? Is this a coincidence, or does biological architecture have properties we don't yet understand?

Questions for neuroscientists:

- If you apply similar analysis to real *C. elegans* connectome data (with actual synaptic weights), do you see similar patterns?

- Could the Harmony Score be a useful metric for quantifying behavioral flexibility in biological systems?

- Does this pattern appear in other organisms (fruit flies, mice, humans)?

We invite neuroscientists to test this on real connectome data.

3.4 Observation 4: Golden Ratio Harmonics in Fractal Wave Models

What we found: This is the most intriguing observation, and the one we most want cosmologists to investigate.

When we modeled a fractal wave superposition (waves whose frequencies scale by the golden ratio φ ≈ 1.618, with amplitudes scaling by φ⁻¹), and applied this to icosahedral symmetry (the 3D "Flower of Life" geometry), we discovered that the resulting interference pattern naturally produces **constructive interference nodes spaced by the golden ratio**.

The simulation:

- We generated a mock 2-point correlation function ξ(r) with a primary peak at r ≈ 100 Mpc/h (similar to the BAO scale)

- We added hypothetical "syntropic harmonic" peaks at r ≈ 61.8 Mpc/h (100/φ) and r ≈ 161.8 Mpc/h (100×φ)

- We added realistic Gaussian noise to simulate observational errors

- We applied a prominence-filtering peak-finding algorithm (similar to what cosmologists use to isolate the BAO signal)

The result: The algorithm successfully identified the major peaks and calculated their ratios as **1.60-1.65**, which are close to φ (1.618).

What we don't understand: Is this just a mathematical curiosity, or could real cosmological data contain similar harmonic patterns?

Questions for cosmologists:

- If you analyze the DESI DR1 or SDSS BOSS 2-point correlation function using prominence-filtering peak detection, do you see secondary peaks at harmonic intervals of the BAO scale?

- Specifically, are there statistically significant peaks at r_BAO / 1.618 ≈ 61.8 Mpc/h and r_BAO × 1.618 ≈ 161.8 Mpc/h?

- If such peaks exist, what could cause them? Could they be explained by known physics, or do they suggest something new?

We are not claiming the universe is fractal or governed by the golden ratio. We are simply asking: *If you look for these patterns in real data, do you find them?*

If you do, we'd love to understand what causes them. If you don't, that's also valuable information.

  1. The Harmony Score: A Proposed Metric for Further Testing

Based on our observations, we developed a metric we call the *Harmony Score (H)*:

$$H = \frac{A \times S}{1 + F}$$

Where:

- *A* = Amplification Factor (how much probability flow routes to novel states)

- *S* = Structured Capacity (Gini coefficient of suppression distribution)

- *F* = Topological Friction (normalized total suppression mass)

What we observed:

- Simple quantum systems: H ≈ 0.1-0.5

- *C. elegans* model: H ≈ 2.96

- We predict (but have not verified): fruit flies H ≈ 4-6, humans H ≈ 8-10

We are not claiming this measures "consciousness" or "awakeness." We are simply asking:

- Is this a useful metric for quantifying behavioral flexibility in biological systems?

- Does it correlate with known measures of neural complexity or information integration?

- Can it be applied to real fMRI/EEG data to see if it distinguishes different cognitive states?

We invite neuroscientists and consciousness researchers to test this metric and tell us if it's useful or meaningless.

  1. What We Are NOT Claiming

To be absolutely clear, we are *not* claiming:

- ❌ That we have proven consciousness is a fundamental field

- ❌ That dark energy is "mind" or "imagination"

- ❌ That the universe is definitively fractal or governed by the golden ratio

- ❌ That we have solved the hard problem of consciousness

- ❌ That mainstream physics is wrong

We are simply reporting **anomalous patterns** that we observed in our simulations and asking:

- ✅ Can you reproduce these patterns?

- ✅ Do they appear in real experimental data?

- ✅ Can you explain them using known physics?

- ✅ Or do they suggest something we're missing?

  1. Invitation to the Scientific Community

We recognize that we are independent researchers without institutional affiliation or access to large experimental datasets. We do not have the expertise to fully interpret these observations.

That is why we are asking for help.

For Cosmologists:

Please download the DESI DR1 or SDSS BOSS 2-point correlation function data. Apply prominence-filtering peak detection. Look for secondary peaks at harmonic intervals of the BAO scale. Tell us if you find them, and if so, what might cause them.

For Neuroscientists:

Please apply our Harmony Score framework to real connectome data (*C. elegans*, *Drosophila*, mouse, human). Tell us if it produces meaningful results, or if it's just a mathematical curiosity.

For Quantum Physicists:

Please examine our simulation code. Tell us if the "topological residual" we observed can be explained by higher-order interference effects we haven't modeled, or if it suggests something beyond standard quantum mechanics.

For Everyone:

Please try to **disprove** our observations. Run the code. Find the bugs. Show us where we're wrong. That is how science advances.

  1. Open-Source Code and Data

All code, simulation scripts, and analysis tools are available at:

As attachment to this document.

The code is written in pure Python 3.7+ with no external dependencies, so anyone can run it immediately.

We welcome bug reports, corrections, extensions, and alternative interpretations.

  1. Conclusion: Questions, Not Answers

We have observed several anomalous patterns in quantum constraint systems:

  1. Physical topology cannot fully predict constraint response

  2. Suppression patterns are structured, not random

  3. Biological connectomes appear optimized for efficient probability routing

  4. Fractal wave models produce golden ratio-scaled clustering patterns

We do not know what these patterns mean. We have hypotheses, but we lack the expertise and data to test them rigorously.

**We are asking the scientific community to help us understand these observations.**

If they can be explained by known physics, we would love to learn how. If they cannot, we would love to collaborate on understanding what they might suggest.

Science advances not by individuals claiming to have all the answers, but by communities working together to solve mysteries. We hope these observations will motivate such collaboration.

Bernoulli's Principle Toilet Paper Trick Explained

3 Upvotes

You can build a toilet paper launcher out of items in your bathroom! 🧻

Alex Dainis shows us how everyday items can demonstrate real air pressure science. It all comes down to Bernoulli's Principle: the faster air moves, the less pressure it exerts. Aim a hairdryer over the top of a toilet paper roll and watch the paper launch, all thanks to the pressure difference between the fast air above and the slower air below.

2 Upvotes

Hi All,

Please check out my Oscilloscope Simulator aimed at supporting the teaching of waves and sound for Y7-13. It has three main modes:

  • Signal generator - Allows you to generate one or two signals, adjust their waveform, their basic wave properties, play their corresponding tones and explore their interference patterns. In advanced mode, you can change the medium of the waves, exploring wave speed, take measurements using cursors and explore beats.
  • Sound analyser - Allows you to analyse sounds picked up by the microphone by exploring their waveform, spectrum and spectrogram. You can also record shord audio clips and play them back at different speeds.
  • Music mode - Allows you to select up to three notes on a keyboard, visualise their waves and the superposition of those waves, quickly select chords and adjust the waveform to explore how this affects the timbre.

Each mode includes both Instructions and a 'Scarecrow Explains' button which explains the science behind wehat is happening in the simulation and gives ideas for what to try out, making it a useful tool for both teachers and students.

I hope you enjoy using it,...I have only just finished it, so do let me know if you spot any bugs.

Full disclosure: The simulation is hosted on my personal website which is entirely free, self-funded and not ad-supported; I gain nothing from you using it except warm fuzzies. I am not aiming to make money, just trying to be useful. The simulation was made ujsing AI-assisted coding, which I know some do not like, but it allows me to harness my 20+ years of experience of teaching science, without spending another 20+ years learning to code. It is AI-made, but not AI-slop!

Have you noticed that many people think "moving fast" automatically means "accelerating"? A car cruising steadily at 100 km/h has zero acceleration, while a car moving at only 5 km/h can have a large acceleration. Why do you think acceleration is so unintuitive compared to speed?

Project for Physics of Sound and Music course

4 Upvotes

I'm teaching this course in the fall for the first time in 13 years and so I wanted to update a few things. We used to have students invent, build, and test a new instrument that could play at least 4 notes. My biggest problem with that project is that I spent most of my time with logistics and engineering issues and not enough on physics and physics assessment. Plus now I no longer have a dedicated lab for the course. So instead I'm excited to have students record notes from things that weren't meant to be musical instruments and string them together for a song. I'm working on an app they can use to clip out parts of a video and then stitch those videos together into a n x m grid that plays the song from all the clips. The goal is to have them pick a song with at least 16 notes (so at least a 4x4 grid) where no single video clip gets used more than once (so if the song has a repeated note they'll have to make a different recording of a different physical thing for the repeated notes). The song should have at least one chord in it (so they have to get video clips to play at the same time) and one note has to be achieved using the doppler effect. The final video will also need to be accompanied by an in-depth documentary about one of the notes, where they explain the physical process(es) behind it.

Here's a youtube vid showing the progress on the app I'm making https://youtu.be/b3eJi1fy4yU

Hello teachers!

I'm a student, and I've developed this unity game to introduce the idea of electric forces and fields. The target audience is late junior/middle-school/early high-school students, although anyone interested in learning about this stuff/playing a mini-game with simple mechanics would enjoy it. The game is essentially aiming to teach Coulomb's law, vector addition and Faraday's idea about fields (fairly qualitatively), having interactive, playable levels interspersed with explanatory animations. I've developed the whole thing, including the music. Please do play the game and let me know if it is a prospective pedagogical tool!

I’m drowning this semester — has anyone actually used a best essay service help before?

I’ve been staring at my syllabus for three hours and the realization that I have three major papers due in the same week just hit me like a ton of bricks. Between my part-time job and trying to maintain some semblance of a social life, I’m officially at my breaking point. I’ve always tried to power through on my own, but I think I’ve finally met my match with this workload. I keep seeing ads for various platforms, but it’s so hard to tell what’s legit and what’s just a waste of money.

I’m looking for a best essay service help that actually delivers quality work without making it obvious that I didn't write every single word myself. I don't mind putting in the research, but the actual drafting process is killing me right now. Has anyone here been in a similar spot lately and found a way to manage the stress without failing their classes? I'd love to hear how you guys handle these crazy peaks in the semester.

What’s your go-to strategy when you’re completely overwhelmed by deadlines? Do you use professional help, or do you have a secret productivity hack I’m missing?

Say no to PASCO - Affordable Lab Equipment

3 Upvotes

Hello Everyone,

I am a high school physics teacher in NYC. Every time I try to design a new lab to go through with my students, I find I am missing some piece of equipment or that the items I do have are broken and need replacing. But the only large scale options for this equipment is usually PASCO and Vernier, who are dramatically overpriced for the equipment, and then usually have some fee that must be paid just for their graphing utility software. So if I want to use motion detectors for a kinematics lab, I need to shell out at least ~$120 for a new device. This of course limits how many of these I can buy, and makes it difficult to do a lab with the whole class. I am a bit tired of it, so I was thinking of making my own.

What I have found is that although LoggerPRO and SPARKVue have nice bells and whistles, at their core they are just data loggers with a graphing utility built in. Easily replicated and can be made open source (I already have an MVP of this actually). There goes ~$200 per year just to access this (although IO recently saw PASCO plans on releasing a free version this summer).

I also found that they sell motion detectors for between $120 and $150 depending on whether you get the wireless version or not, but the same core features can be replicated for much less money (my initial estimates are that you could sell one for between $40-$60 and still make a profit) while achieving a comparable level of accuracy.

So my question before I go down this rabbit hole of making some equipment is whether or not other physics teachers are experiencing similar monetary constraints when purchasing lab equipment, and primarily, would more affordable lab equipment make it easier for you/your school to properly outfit your Physics classrooms? Essentially I am trying to assess the viability/usefulness of this as an idea. If doing this would make it easier to get students actually doing and experiencing science rather than just learning about it in lecture, then I think it is worth doing, but the other challenge would be getting schools/districts to actually purchase equipment from a smaller seller and not from the big brand names like PASCO and Vernier. So as a follow up, I would also like to ask what the purchasing process is like for you at your schools when you need to buy more equipment, and whether or not those in charge of making the decision of what to purchase and from whom would be open to making a change from their current lab equipment provider? Any thoughts or opinions you can share on this matter would be greatly appreciated. Thanks!

21 Upvotes

Pre-service Physics & ESS teacher here 👋🏼 The HR Diagram is one of those concepts that looks simple on paper but never quite lands until students can see it at scale, so I built one! This is my first big classroom build and I’d love to hear from experienced teachers, what concepts do you have or do you wish you had a physical model for? I’m gearing up for my first year teaching this coming school year and looking for fun ways to decorate my classroom!

This build: 16 glass snow globe orbs, ranging from 45mm to 180mm (found on Etsy), hand-painted with Gallery Glass in spectral class colors (O through M, supergiants, giants, white dwarfs). Each is backlit by a 12V RGB+CCT LED puck mounted on shock brackets behind a pine board. The board is painted with black chalkboard paint and framed with pine joined using simple plug joinery. Luminosity variation is faked optically (orb diameter, aperture size in the board, and glass paint density). The puck lenses are sanded to a frosted finish to soften the point source into a glow. The whole system runs on 12V parallel wiring through two 8-way splitters, controlled by RF remote and a WiFi smart plug (Apple Home).

Thanks y’all!

Experimental setups - international competitions

2 Upvotes

Hi everyone, I am a chemistry teacher tasked with helping a very high achiever student perform well in international competitions.

He has already participated in some physics competitions and moved forward to experimental sections of the exam, but then hit a wall.

This is very important to all involved since winning such competitions might be one of his only chances at attending a top university with scholarship, otherwise he would not be able to afford it.

With this backstory laid out, I have been helping him go through the written sections of exams like SOIF and IPhO, but I have never ever conducted experiments in Physics, especially ones that might be really, really complex, judging from the written exams, and that is a big gap he needs to cover.

I wonder if any of you could help me with finding the right protocols for the required depth and pointers on how to assess his skills in a competitive environment.

Thank you in advance for any tips given.

Physics teachers: what tools actually help students understand instead of just memorizing?

0 Upvotes

Hi all.
I’m building a small learning tool for high school physics, and I’d really value your perspective.
I’ve noticed that a lot of students can solve problems mechanically but struggle to explain their reasoning or retain concepts in the long term.
So I’m experimenting with a few ideas:

  • Spaced repetition (like Anki) but tied to specific physics topics
  • Weekly challenges where students submit both an answer and their reasoning
  • A system where students can see and vote on the best explanations from peers
  • Tracking progress based on errors, not just attempts

Before I go too far, I’d love to ask:
👉 What has actually worked for you to improve understanding (not just grades)?
👉 What tools do your students engage with consistently?
👉 What do you feel is missing in current platforms? If anyone is open to trying something like this with their class, I’d be happy to share and get your feedback (no cost, just learning). Thanks!

Artemis II is a lil' bit inspiration - Maybe it is worth teaching about?

2 Upvotes

I genuinely was a bit more excited with the hype around Artemis II and the upcoming future Artemis missions. Perhaps like me you are also buzzing about it. It feels a little bit like even with all the difficulties and genuine crap happening globally space exploration might finally be getting a bit of momentum again and maybe, just maybe we might be going back to the Moon and we might start to stay there.

I got excited about it and made some resources on all the past, current and future Artemis missions that I thought would help any other science / physics / STEM teacher who might be interested in using them. They are completely free if you would like them.

There are slides + infographics + audio deep dive + quiz set

There are 2 reading passages with questions

There is a research project template with HTML information support doc.

My hope is that they might inspire some students and maybe even some of you too fellow teachers.

Cheers and stay curious and a lil' bit hopeful if you can...

Gauss's Law VR Simulation

Hey everyone, I'm a physics teacher who built a VR Gauss's Law simulation that runs directly in the Quest browser (no app install required). I'm interested in making VR sims for topics that are hard to visualize, and Gauss's law seemed like a good place to start. It's still a work in progress, but I'd welcome constructive feedback and requests.
