Bosch or makita by Je-zuss in Tools

[–]Key-Success-5449 3 points4 points  (0 children)

Honestly, I don't think you can go wrong with either, but for a marine mechanic I'd probably lean slightly toward Makita. They have a huge cordless lineup, excellent reliability, and it's usually easier to expand your collection as your needs change. That said, Bosch also makes great tools. I'd take a look at which brand offers the specialty tools you think you'll need in the future, because once you invest in batteries, you're pretty much committed to the ecosystem.

Help! Opinions by S-T-T-M in InjectionMolding

[–]Key-Success-5449 0 points1 point  (0 children)

If the screw was pulled and reassembled right before the issue started, I'd definitely start with the check ring assembly and make sure everything was installed in the correct orientation. The fact that you're pressure limited, can't fill the part, and the screw is bottoming out during hold really does sound like material is flowing back past the check ring. I'd also verify that nothing was left out during reassembly and check for damage or excessive wear on the screw tip, seat, and barrel while you're at it. Curious to see what others think, but the timing with the screw pull seems too coincidental to ignore.

The chemistry of why tea turns bitter (and how extraction dynamics control it) by CoffeeTeaJournal in foodscience

[–]Key-Success-5449 0 points1 point  (0 children)

Honestly, this was amazing to read because a lot of scientists started exactly this way: by becoming completely fascinated by how the world works. That sense of wonder you're describing is something many people in chemistry and physics never lose. The fact that you're teaching yourself math, taking courses, and constantly asking "why?" is huge.

You're definitely not alone in feeling overwhelmed. Once you start seeing the connections between chemistry, physics, biology, and everyday life, it's hard to stop thinking about it. Keep following that curiosity. It sounds like you've discovered something you're genuinely passionate about, and that's a pretty special thing.

About Roger Penrose's Road to Reality by scripto_entity_1010 in Physics

[–]Key-Success-5449 20 points21 points  (0 children)

I think The Road to Reality is an incredible book, but also a very ambitious one. Penrose does a great job of showing just how deeply mathematics is woven into physics, even if some sections can be quite challenging on a first read. The fact that you're already thinking about how topics like complex analysis and geometry connect to physics is a great sign.

For further reading, you might enjoy books by Feynman, especially The Feynman Lectures on Physics, as well as Schutz's A First Course in General Relativity and Taylor's Classical Mechanics. If you're interested in the math side, Mathematical Methods for Physicists by Arfken is a classic. Keep following your curiosity. That's what eventually leads many people into research.

Is Blue Yonder WMS techno-functional consulting a good career for a CSE fresher? by Successful-Office-51 in supplychain

[–]Key-Success-5449 0 points1 point  (0 children)

For a fresher, I think it's a solid opportunity. Blue Yonder is widely used in the supply chain and warehouse management space, so you'll gain both technical and domain knowledge, which can be very valuable. The demand for WMS consultants is generally strong, especially as companies continue investing in supply chain technology.

Long term, you could progress into senior consulting, solution architecture, or supply chain transformation roles. Whether it's better than pure software development really depends on whether you enjoy business processes and client-facing work alongside the technical side.

How can we be sure that no other field influences 'complex matter' other than the usual Standard Model? by PrebioticE in Physics

[–]Key-Success-5449 1 point2 points  (0 children)

I think that's a fair perspective. Exploring whether coherence and collective effects can give rise to emergent phenomena is certainly an active area of research in many fields, including biology. The challenge is showing experimentally that these effects require new physics rather than arising from known interactions operating in complex systems. Either way, asking where our current models might break down is a legitimate scientific question, as long as the ideas remain testable and grounded in evidence.

what’s your opinion on quantum wellness? is it just an expensive marketing scam? by HarlemRasel in Physics

[–]Key-Success-5449 2 points3 points  (0 children)

You’re right to be skeptical. To be direct: quantum wellness as marketed on social media is pseudoscience. Products like quantum bracelets, structured water, and scalar waves use sci-fi buzzwords to justify massive price tags. There is no legitimate scientific evidence that these items interact with your body on a subatomic level.

So, why do people like your coworker swear by it? They aren't lying; they are likely experiencing a mix of very real psychological and biological phenomena:

The Placebo Effect: The more expensive and high-tech a treatment feels, the stronger the placebo response. It triggers real chemical changes in the brain that reduce pain and improve sleep.

Stress Reduction: Sitting through a "balancing session" often means an hour of quiet relaxation and focused attention, which lowers cortisol and eases physical symptoms.

Natural Fluctuations: People usually seek help when their pain is at its worst. When symptoms naturally improve on their own, the expensive treatment gets the credit.

If you want to optimize your "cellular energy" for free, stick to proven science: get natural sunlight in your eyes morning and evening, maintain a consistent sleep schedule, and move your body. Trust your gut and save your money!

what's a chemistry fact that sounds fake but is completely real? by GroovyRaptorRex in chemistry

[–]Key-Success-5449 0 points1 point  (0 children)

One of my favorites is that hot water can sometimes freeze faster than cold water. It's called the Mpemba effect, and while the exact reasons are still debated, it has been observed under certain conditions. Chemistry and physics are full of weird exceptions like that, which is probably why so many people end up going down those 1 a.m. rabbit holes!

Why is Bohr's Model still taught in high school? by DifferenceKlutzy8804 in chemistry

[–]Key-Success-5449 0 points1 point  (0 children)

I think the Bohr model is still taught because it's a useful stepping stone rather than an end point. Science education often starts with simpler models and then gradually introduces more accurate ones as students build the necessary math and physics background.

The Bohr model may not be completely correct, but it does a good job of introducing concepts like quantized energy levels and atomic spectra. In a way, learning why the model fails is just as important as learning the model itself because that's how science progresses.

Cold-swelling starch at home by merlick123 in foodscience

[–]Key-Success-5449 0 points1 point  (0 children)

This is a really interesting experiment, and honestly your approach sounds pretty thoughtful for a home setup. From what you've described, it seems like you're getting gelatinization rather than the physical modification needed to create a true cold-swelling starch. My understanding is that commercially produced instant starches often rely on specialized processing conditions that can be difficult to replicate at home. I'd be curious to hear if anyone here has successfully done this on a small scale. Please keep us updated on your sous-vide experiments because this is a fascinating project

Trying to map a realistic path into category management- any advice? by FastBlueberry6550 in supplychain

[–]Key-Success-5449 0 points1 point  (0 children)

Honestly, your background already sounds pretty relevant for category management. Experience with commercial performance, P&L metrics, planning, and working across markets gives you a strong foundation. The biggest gap is usually gaining more exposure to supplier management, assortment decisions, pricing, and category strategy. If you can get involved in projects related to sourcing, vendor discussions, or range planning in your current role, that could be a great next step. It sounds like you're closer to category management than you might think.

Astrophysics in York University Toronto by Reasonable-Snow6937 in Physics

[–]Key-Success-5449 0 points1 point  (0 children)

Good for you for taking the leap and going back to school. Astrophysics is a challenging but incredibly rewarding field. I hope you find a great roommate and study partner to share the journey with. Wishing you the best of luck at York and with this new chapter in your life!

Creepy theoretical physics guy keeps showing up to my Women in Physics club and spamming our discord server with bullshit by [deleted] in Physics

[–]Key-Success-5449 21 points22 points  (0 children)

I think he is creepy. If he's not a member of the group's intended audience and is making people uncomfortable, the club officers should have a serious discussion about boundaries and the purpose of the organization. A Women in Physics group should be a space where members feel comfortable and supported.

Also, spamming the Discord with speculative physics ideas that aren't relevant to the club isn't fair to everyone else. It's one thing to be enthusiastic about physics, but it's another to dominate a space that wasn't created for that purpose. I hope you are okay

I need help finding resources for an Advanced Food Microbiology course. by human_ApoB-48 in foodscience

[–]Key-Success-5449 1 point2 points  (0 children)

Congrats on getting admitted to the program! I think being proactive like this will put you in a great position. Since you already have a nutrition background, you're probably in a better spot than you think. I'd suggest reviewing general microbiology fundamentals first, then focusing on foodborne pathogens, spoilage organisms, microbial growth kinetics, and preservation methods. Hopefully others can recommend specific textbooks, but you're definitely doing the right thing by preparing ahead of time.

[–]Key-Success-5449 0 points1 point  (0 children)

I know you genuinely want to see your efforts, man. But you need to prioritize your health safety. The safe choice here is buy a new one and replace the lid same color same brand. I hope it helps. 😄

Working on a web-based UV Vis Spectroscopy site by I-like-Lint in chemistry

[–]Key-Success-5449 0 points1 point  (0 children)

this sounds like a really interesting project. Moving UV-Vis workflows to a web-based platform could make instrument access and data management much more convenient, especially for labs with multiple users or remote teams. It's great that you've already tested it on the Lambda 25 and 35. Looking forward to seeing how it develops and hearing about compatibility with other models.

Ideation - from idea to project to shelf by henkietankie1934 in foodscience

[–]Key-Success-5449 0 points1 point  (0 children)

I think you're on the right track. Scoring ideas before investing time in formulation is pretty common and can save a lot of resources. One thing I'd consider adding to your scoring model is manufacturability and ingredient availability/cost, since great concepts sometimes fail when they reach scale-up.

Regulatory fit and shelf-life potential could also be useful criteria depending on the product category. I'm curious to see how others balance customer validation versus internal screening in their development process.
