Weave Robotics: "Humanoids are built from philosophy, not parts"
How we solved the "grouping" problem on our toast packaging line.
Hey folks. Long-time lurker in manufacturing subs, first time posting. We mostly build custom automation for bread&pastry production lines. One common headache when moving from slicing to filling/packaging is getting the right number of slices together without jamming or damaging the product. This is our in-house solution for a gentle side-transfer and grouping mechanism. It's adjustable to output stacks of 1, 2, or 3 slices on the fly. Curious about: What other clever mechanical solutions have you seen (or built) for handling delicate or irregular products on a fast line? Always looking to learn from different industries.

Why do some subway construction projects disturb the surface while others don't?
For context, for most of my life Ive lived in Istanbul and none of the subway lines affect the surface when being constructed (with the exception of stations obviously). However, I've noticed that in Vancouver, during the construction of the Millennium line extension, they dig a trench into the road and have to shut down half of it. you can see the tunnel from the surface during construction. What's the difference?
I don't understand something fundamental about engineering
Hi so this is a bit of a confused questions to begin with, but I'm currently a mechanical master's and I worked for a year, so I got reintroduced to this strange problem i have regarding primarily engineering exams, which is that i HAVE always underperformed pretty badly in them. I always go for active recall, in fact even after the exams, I tried to learn new topics and I'm fine. I can memorize facts pretty well given a few days, my retention is decent I think. I also study consistently, pay attention in classes but my grades seem not to reflect that Am I not studying enough? I tend to study a bit slower, like I don't solve questions from day one i take a few days to read and stuff, but then I solve as many as I can. But I'm losing my grades somehow and it's been a pattern. So the only thing I can think of is somehow I'm studying things the teacher doesn't want me to study, and thus missing out on the things that are important Since I'm in India grades are like everything here, so I really need some answers, Does anyone have the same problem?
Can Bluetooth speakers(small JBLs) interfere with assembly plant robots?
I’ve worked for this big car company for over a decade and they have let us use reasonable speakers, but now they are trying to say we are not allowed to use any speakers(including small JBLs despite sending a letter out days ago saying those ones we could use) BECAUSE the Bluetooth from the speakers are interfering with their robots and it is causing downtime in the line. They’ve never said this happened prior and I was hoping someone can give me an explanation as to how they can/can’t interfere with them? As a big company, every year around this time they come up with new ways to try and get us all written up and fired before they give out profit sharing in a couple months and this is their newest excuse
How do resistors affect energy consumption?
If you put a resistor in line with a light bulb, the light will dim and consume less energy, but will the difference in energy consumption be taken up by the resistor through waste heat? or will the total energy consumption of the circuit be reduced? What would determine how wasteful a resistor is?
State of the DAQ world
Starting a new role and we need to build our test infrastructure from scratch. At my previous role we mostly used Labjack, some NI HW and some custom DAQs built from Raspberry Pi. I’m wondering what the state of the low-medium cost DAQ world is in the year of our lord 2025. Is Laback still king? Has some flashy AI powered startup taken the throne? The advent of AI code assistants has really lowered the bar to getting a raspberry Pi + HAT DAQ system up and running but to my knowledge there are no easy and simple GUIs to accompany these setups. Anyway to reiterate, what’s the hot new flashy DAQ system you’re using and why?

Does EPDM rubber come in liquid form?
I feel like I'm being gaslit by chatgpt right now, it tells me that EPDM rubber comes available in liquid form, but I can't seem to find a commercial product to buy. All the links it sends be contains no useful or accurate info (as usual). I see a lot of liquid rubber products that are compatible with epdm, but non that are actually epdm. Have any of you seen such a product or know of it's even possible? I am specifically looking for EPDM because I am interested in making some custom gaskets/diaphragms that will be used with DOT fluid and need the chemical resistance.

Strong floor vibrations from upstairs neighbors - how to tackle it?
Hi everyone, I live in a concrete apartment building with laminated floors. Lately, I’ve been feeling strong short jolts/vibrations in my bed, especially late at night, whenever my upstairs neighbors walk. They say they are just walking normally and not making unusual noise. It’s not constant - more like sudden shocks - but enough to disturb my sleep and be very tiring the next day. I’m trying to understand how this is possible. Could normal walking really cause such strong jolts, or might there be some construction or structural issue in the building? What is crazy, is how it shakes my bed, even though I placed it on two standard rubber pads. It feels it offers only minimal dampening. Also, somehow it doesn't really happen in the summer, but gets more severe in the winter, with this autumn being the worst. 1. Has anyone experienced similar strong vibrations from neighbors who are “just walking normally”? 2. Any practical ways to reduce or dampen these vibrations in a bedroom? I’m looking both for explanations for why this happens and solutions to make it less disruptive. Thanks in advance!

Question for Oscilliscope Clock Project
Designing a "high speed yacht"
I am designing a "high speed yacht", well rather basing it off an existing design. (Personal model/design project) Its 310ft long (300ft pp), 37ft beam, 11ft draft, at about 1,800 standard tons fully loaded (prepared for transatlantic crossing) The original power plant was 12,000 hp between two shaft/propellers, at a max speed of 24-26 kt. Cruising speed is about 15-20kt. Range of 4,500nm at 15kt with fuel load. I want to increase max speed to about 27-30kt. The power plant I'm looking at has 11,500 hp PER shaft. Would it be able to get to that max speed with that power plant? Would I still be able get that if I were to increase the length up to 320ft and tonnage up to 2,100?

AI News Anchors Are Here What Happens to Trust, Jobs, and Reality?
In the last year or two, it feels like we’ve gone from “AI can write a draft” to “AI can be the face of the newsroom.” I’m not talking about sci-fi. I mean realistic video presenters, cloned voices, auto-summarized breaking news, and entire short-form news clips generated from a single article. On one hand, this could be genuinely useful: - Faster multilingual news delivery - Better accessibility (captions, translation, summaries) - Lower production costs for small outlets On the other hand, it also opens a bunch of weird doors: - “Confidently wrong” clips spreading faster than corrections - Deepfake-style misinformation that *looks* like a legit broadcast - The erosion of accountability (who is responsible when the “anchor” lies?) - Job displacement across editing, voiceover, production, and even reporting workflows The part that fascinates (and worries) me most is the trust layer. Humans already struggle to separate real news from manipulation. If the *presentation* becomes fully synthetic, the “vibe of credibility” can be manufactured too. So I’m curious how people here see this playing out: 1) Should AI-generated news presenters be clearly labeled (like nutrition labels for media)? 2) What’s the minimum standard for verification before an outlet publishes AI-generated clips? 3) Do you think audiences will adapt quickly (“I don’t care who reads it”) or will trust collapse (“I don’t believe anything anymore”)? 4) If you ran a newsroom, what would you automate — and what would you *never* automate? I’m not anti-AI. I’m just trying to figure out what reality looks like when the news itself becomes a product you can generate on demand.
In your opinion, will Gen Alpha’s hardships and economic struggled be more challenging than the generations before them?

So bioviva faked their dementia cure, charged money for it, and NOBODY's going to jail??
it looks like bioviva is still selling their “dementia cure” that they now KNOW doesn’t actually work, and i don’t know why nobody’s stopped them. there’s an [article about them on Wired](https://www.wired.com/story/bioviva-gene-therapies-liz-parrish-longevity/), it discusses an elderly woman who travelled to Tijuana for their gene therapy, and this feels much grubbier now that their research got [exposed for being fake](https://retractionwatch.com/2025/08/13/george-church-bioviva-rutgers-pnas-retraction/). why would they fake the research if it works? they must know that it doesn’t work yet they’re STILL selling it\! they weren’t even subtle about it, check this out: I copied the transcript from their talk at [RAADfest in 2022](https://www.youtube.com/watch?v=MIyjFN1kmws) into ChatGPT to find that quote where BioViva said that they’ve cured dementia, but ChatGPT freaked out over the text trying to check whether what she was doing was actually legal. literally, it freaked out in the middle of its chain-of-thought, trying to explain to itself how they weren’t doing anything illegal. they served [carcinogenic junk](https://www.theguardian.com/science/2016/jul/24/elizabeth-parrish-gene-therapy-ageing) to elderly people and said it would cure their dementia. they knew their treatment could cause cancer, and they sold it anyway. this entire shtick was for the [sake of a dodgy research study](https://retractionwatch.com/2025/08/13/george-church-bioviva-rutgers-pnas-retraction/) that was taken down because someone faked the pictures. they should all go to jail. yes, jail now, i think jail. all of the advisors, the founders, anybody who promoted this shit: jail. the founder is a test of patience, apparently we’re sooo much more stupider than mensa queen Elizabeth Parish that billions of dollars and the combined efforts that every other team was USELESS that’s [LITERALLY WHAT SHE SAID](https://www.prnewswire.com/news-releases/dementia-patients-receive-dual-gene-therapy-show-cognitive-improvements-301427335.html) but her magic lizzy lizzy touch can cure dementia yeah-JAIL NOW YOU JARGONIZING ELIZABETH HOLMES FANGIRL. I don’t give TWO ISHTS what country her study was conducted in, the only question we need to be asking is ‘when jail’? I swear, there needs to be some accelerated procedure for this… i do NOT care what the law is in Mexico and i’m tired of VCs feeding Elizabeth Parish money constantly to help her betray the people that put their trust in her. jail NOW.
What would you expect to be the most popular mobile ground robot body plan(s) by 2050?
I'm excluding drones, both of the quadcopter type and the Starscream/fighter jet type, as those are widespread already. Personally, I'm expecting wheeled semi-humanoids to be pretty widespread alongside tracked vehicles (tanks) and maybe wheeled vehicles (cars) if they are adapted to navigate uneven terrain. I do think that there will be some overlap and modularity in the next 25 years, but I feel like semi-humanoids and modified cars and tanks will be at least three of the top four most widespread designs. Disclaimer: Not an expert, just someone who's interested in following the less immediately depressing parts of the news.
Innovation Shifts to Renewables: Swedish Structural Battery Breakthrough Marks Fossil Fuels’ Decline
An under-appreciated aspect of the switch to renewables & electrification is how it is getting all the innovation. Will you see major technological innovation advances like this for the dying paradigm of fossil fuels? No you won't. Their death spiral has already started. Swedish researchers say they have made a major advance in structural battery tech, that will allow the structure of EVs and electric aircraft to store energy, not just their batteries. They've developed a composite that uses carbon fibers as both structural reinforcement and electrodes/current collectors, minimizing dead weight. A load-bearing electrolyte enables ion transport while transferring mechanical forces. Glass fiber fabric separates the carbon-fiber negative electrode from an LFP positive electrode on aluminum foil. The material delivers ~24 Wh/kg energy density, ~25 GPa modulus, and >300 MPa tensile strength, surpassing prior structural battery materials in both mechanical and electrochemical performance.

Soft / People skills in work 2045 – Importance of human skills in future work
Hi everyone, I’m writing a research paper for my bachelor’s program (Sustainable Economics & Management) and I’d love to collect some perspectives, hot takes, sources - whatever comes to your mind! I already looked into some "future scenario papers" by the OECD and PwC, which are giving me some input, but I am searching for more diverse and independent takes on this topic (which is super interesting to me). **My Assumptions:** – Remote work continues to grow – AI increasingly talks to AI via. agents – “Base work” (coding (like coding coding), writing, summaries, meeting prep) gets normalized through AI – Humans gain more time for non-routine work **Open question:** **What happens to the importance of people / soft skills in that world?** e.g. Empathy, conflict handling, communication like feedback skills, presentation, leadership? Looking forward to your inputs here - thanks so much in advance and wishing you all relaxing cozy holidays :) Best regards, Momo

Why does the rest of the world have to go to so much trouble to protect billions of people from a tiny number of bad people?

Satellite collisions in space and a recent near miss between a Chinese sat and a Starlink sat
Stumbled across the following tweet from the VP of Starlink engineering and thought it was worth highlighting: *"When satellite operators do not share ephemeris for their satellites, dangerously close approaches can occur in space. A few days ago, 9 satellites were deployed from a launch from the Jiuquan Satellite Launch Center in Northwestern China. As far as we know, no coordination or deconfliction with existing satellites operating in space was performed, resulting in a 200 meter close approach between one of the deployed satellites and STARLINK-6079 (56120) at 560 km altitude. Most of the risk of operating in space comes from the lack of coordination between satellite operators - this needs to change."* https://x.com/michaelnicollsx/status/1999630601046097947 There's a space.com article too: https://www.space.com/space-exploration/satellites/spacecraft-from-chinese-launch-nearly-slammed-into-starlink-satellite-spacex-says

I am reading *Ignition!* by Clark and Asimov and I am searching for books which would clear up all/some of the following questions: - Why are nitrogen compounds so reactive? - Why is furfuryl alcohol, aniline and especially hydrazine so suitable for hypergolic rocket fuel? - Why does adding sulfuric acid to nitric acid sometimes help combustion? - What is an endemic mixture? - What are the exact reactions between RFNA and the hypergolic fuels? **Context**: I am a physicist and had organic/anorganic chemistry but I am not so fluent in these fields as to understand the reasoning behind choosing nitrogen based fuels and all of the stuff above.

I spent days digging through NASA/ESA archives from the 70s–90s — made a small video from the footage
Hi everyone, I had this idea of a video in my head containing some of my favorite bits of NASA and ESA archival material, especially the older stuff from the late 70s to early 90s. Iended up cutting together a small video using the material I found. To keep the atmosphere consistent, I made an ambient/electronica soundtrack for it. I hope you enjoy the footage and vibe - let me know if there are things you would like to see put together with the right ambient sounds to go along with it. Really open for further ideas, as this project was a lot of fun already :) Enjoy
Geminid Meteor Shower viewing times
Question for you all. If I were to see the meteor shower tomorrow on Friday, December 12th, how would this compare to the peak on December 13th? Assuming under ideal lighting conditions, and the time of night being similar; roughly 12:00 - 2:00 am. I’ve seen before that the Geminids shower’s has a high zenithal hourly rate of 120. What am I potentially missing? Thanks for your input!

Why Your Brain Sees Size Wrong
Think your brain sees the world clearly? Think again. 🔍 Alex Dainis explores how optical illusions like this one reveal the science of visual perception, from motion parallax to the way our brain interprets distance and size based on visual context.
Side questing to chemistry
I recently visited a beauty lab that was formulating a an improvement of a new skin care product. I was new to that environment and learning about HCL on the skin was interesting. Apparently it works like a motion sensor to your facial movements drawing in moisture to those areas, smoothing fine lines and filing micro gaps. I found out about filling micro gaps on Stanford Advanced Material https://www.samaterials.com/hyaluronic-acid.html As normie, finding out about all the other uses is incredible especially that I choose finance early and recently my interest in chemistry has piqued.

Question about this process?
If someone has dark skinned parents but is born fair skinned and blonde hair is there a chance even without much sunlight but primarily due to genetic factors both his hair and skin colour could gradually darken during adolescence and puberty?

PPKTP
Sometime back I had to learn how to combine YAG laser with periodically pooled lithium niobate to achieve the process of second -harmonic generation. My search for sources with wavelengths greater than 1000nm finally came to an end when I acquired some from Stanford Advanced Material: https://www.samaterials.com/nlo-crystals/2518-periodically-poled-lithium-niobate-crystal.html. That's for more info if want to check it out. I will come let you know how the light modulation process will go. I'm a bit excited.

Want to Age Slower? Travel Near the Speed of Light
Want to slow down aging? 🕒 Astrophysicist Erika Hamden breaks down a mind-bending reality of motion and time: the faster you move through space, especially near the speed of light, the slower you experience time. This effect, known as “time dilation”, means someone traveling at extreme speeds would age more slowly than people staying on Earth. This project is part of IF/THEN®, an initiative of Lyda Hill Philanthropies.
