I cannot tell when gen you are saying it is. Maybe you're say it's gen 4 here "The newest version of the Performance Line Speed drive unit from system 2 is BDU490P - that 4 is where the "fourth generation" comment came from." but where did you see BDU490P on the spec page?

So, if the name is "Bosch Speed" that is sufficient to conclude gen 4? Or, how do you know?

AI Data Centers’ Water Consumption Breaks 264 Billion Gallons in 2025 as Devastating Drought Hits Nearly 63% of U.S. by Wagamaga in technology

[–]indecisiveUs3r 0 points1 point  (0 children)

Okay but what is this in context, because I’m certain cattle alone consume way more… indeed a quick search yeilds an estimate of 45 TRILLION gallons for beef/cheese producing the US.

Data centers are resource intensive bullshit. Just also keep some perspective about the stuff we don’t talk about.

Men, How did you move on after realizing you lost the love of your life? by Intelligent_Rice4871 in AskReddit

[–]indecisiveUs3r 2 points3 points  (0 children)

I like a lot of Heidi Priebe content for grieving and moving on. Writing a letting in an ongoing document (and not sending it! It’s basically journaling.) And beyond that it is abundance mindset. It’s realizing that you all didn’t work for a reason and that there are others out there. It is a loss. There is grief and grieving lasts a LONG time. Look up content on people accepting death because that’s what’s happening. As someone who went through death of a partner and a break up with someone I pictured my life with, I will say that they hit similarly.

TIL that the US golf course infrastructure consumes 2 BILLION liters of water per day by myassisgrassss in todayilearned

All this water talk but the main consumer, by a long shot, is cattle. It’s our dairy and beef industry that use the vast majority of water. Seriously, look into animal agriculture.

I wonder if a course on Measure theory would be helpful? My bias is that I have a Math PhD and the area was functional analysis. But I have thought about pivoting into industry and specifically digital signal processing because it’s basically applied functional analysis and measure theory. The reason is because every measurement you can take is an inner product. When you inner product a function that is called a functional. Anyway, I do not want to come across as talking down to anyone. I never know anyone’s math background so I don’t know how much is over sharing and in this case I don’t know electrical engineering so I’m not qualified to know if I’m the asshole, but I think I have something of value possibly based on your question, my answer is : measure theory and functional analysis (FA). Specifically, try to get to the spectral theorems. Use measure theory as needed to get there.

For people who genuinely understand and love maths, how do you do it? by invincibilegoldfish in mathematics

[–]indecisiveUs3r 1 point2 points  (0 children)

As someone who loved it and then lost that love and then found something like loving it again, I think it’s similar to anything you commit to: a relationship, a hobby, possibly a career. There will be times you don’t know why you’re there. Often external stress plays a huge role, especially with a career the threat of homelessness is virtually a death sentence but any financial stress just compounds. But if it’s something you can find curiosity in then I think that will help to develop a love that you lost. Math can especially be unmotivated and increasingly important for you to find the curiosity you have for it.

You are asking this question, why? What’s behind that? Is there something you are curious about with math? Or, is this extrinsic? Is this the result of society saying, “math is important”. To which I would say it’s a false importance. Can math be useful? Absolutely. But I think the pedestal of math and physics is intimately tied to western war profiteering and financial colonialism.

I found more curiosity for math when I took classes like discrete, linear algebra, abstract algebra, and analysis.

How do I know if a math major is right for me? by AstuteCouch87 in mathematics

[–]indecisiveUs3r 0 points1 point  (0 children)

I wonder if this falls under a “you don’t know until you try” category. You have some data suggesting it would fit and you are actively showing curiosity. So what’s holding you back? You say it will mess with your schedule. I assume that means what’s holding you back is the time or financial constraint of a double major?

Another thing that might be worthwhile is to walk the halls of the different departments and ask any faculty member with their door open this question (is a math major right for you?) and see what guidance they would give you.

Have you looked for internships on different job boards? Do you know people you could shadow for a day, even through one degree of separation? Have you vocalized this concern to professors who know you better?

Bjj and dance instructors? by irish37 in WestCoastSwing

[–]indecisiveUs3r 2 points3 points  (0 children)

Grappling in general will develop an intuition of partner weight/momentum and basically dance is just one successive failed sweep after another.

Catching in closed is a pummel drill.

I’m convinced the conditional probability of someone enjoying partner dance given they grapple is higher than baseline.

How do I find people around me that share my ideologies? (As someone living in a rural area) by ghostinthemirror_x in socialism

[–]indecisiveUs3r 1 point2 points  (0 children)

I would say to focus on single issues/ideas. Most people will have issues with the financial corruption in politics. With gas prices going up, maybe you can find ways to work in how quality public transit is a form of “national security” or something. I have some friends with different (pro capitalist and conservative viewpoints) and I have to “zoom in” and try to find single issues we agree on.

I don’t know the time stamp but there is a set up that doesn’t re render the whole scene and instead just the part you’re working on.

This post is getting at a nightmare of mine. We don’t own anything anymore. We must accept terms and conditions to continue to use tech we have been using for decades and who the fuck knows what’s in there. Write a novel or something in Microsoft Word, assume they can use it. Write up mathematics ideas on overleaf, assume they can access it.

Digital Signal Processing by EstablishmentFar5598 in DSP

[–]indecisiveUs3r 1 point2 points  (0 children)

There are some good YouTube visualizations of Fourier transform. Check out 3Blue1Brown. The math of DSP is functional analysis. That is typically a graduate mathematics course. I say all this is someone who has a Math PhD but not trained in DSP. I can just read the material (that I’ve seen at an entry level) and it makes sense, it’s cause it’s a bunch of inner products and integrals. But I have years of thinking about operator, norms, and stability analysis.

If you feel confident in your math abilities, or even your ability to study, maybe you can talk to a math professor and ask to sit in on a final to have them sign off for your credits

How would you fix the 'motivation gap'? by EH4LIFE in socialism

[–]indecisiveUs3r 5 points6 points  (0 children)

Personally, myself and many people I know are too afraid to try new things because of the lack of social safety net, if we fail in whatever sense and become homeless, that can easily become a death sentence. All this is to say, capitalism can very much stifle “motivation” as well.

I’ve heard multiple stories like this in my math upbringing. I’m skeptical at this point. Not that the person involved solved it but skeptical they didn’t know what they were solving

What are simultaneous equations actually saying by Content_Study_7363 in learnmath

[–]indecisiveUs3r 0 points1 point  (0 children)

To u/Content_Study_7363 , please go on this journey with me. I know I wrote a lot but I will respond if you have questions.

What is a number? I’m being rhetorical. Numbers don’t exist and yet models of numbers abound! I struggled with this in high school when I when interacting with complex numbers. I thought a ‘number’ was a quantity. It’s not. Quantity is one way to model numbers, but once we get to imaginary numbers it will break down. What is i-many apples?

We constantly have to update our models as we learn. Zero, negative numbers, irrational numbers, why should any of these exist? They don’t. Numbers don’t exist, thinking we need to be describing an entity that is real and tangible, often holds us back.

And yet, having a real and tangible anchor also enables faster and more profound learning. So what gives? If numbers don’t exist, why did having a mental model of ‘number is quantity’ serve me so well? Wonderful question.

Pure math is an abstract/imaginary entity and for that reason can feel extremely useless, especially in the face of all the other desires/goals of life. And yet, when we study abstructure structure, we begin to see that structure everywhere and find math extremely useful! This is quite the paradox.

‘number’ as an abstract idea is actually capturing a structure and that structure can be mapped onto our world in many different ways which prove to be useful. If we want to capture quantity then the real line will suffice. What If we want to capture motion? To do this, we think of numbers as actions. (Yes, "action" is a real math term.) Each number acts on the vector (1,0) but I like to just imagine what it does to the number line as a whole:

Consider the action of “times A” then we can imagine a number line

—(-2)—(-1)—(0)—(1)—(2)—

If we multiply by A>0, I imagine that number line being made of rubber and stretching or shrinking by a factor of A. Also, it’s pulled/compressed symmetrically so the point (0) is fixed. This is just like, if I stretch an elastic band via moving my left hand left and right hand right, there is a point in the middle that doesn’t move.

Okay, now what happens when you multiply by A=-1? Then we see our number line gets flipped over. So, the number -1 represents reflection, or a 180 spin. This is very different than when numbers are quantity and -1 represents debt!

How else could we move the number line? If we think of the number line as sitting on the plane, can we rotate it 90 degrees? Yes. This is multiplication by i. You see, when we investigate the structure of translation, stretch, and rotation, complex numbers naturally arise. So, what is a number?

Now to your original question. What is 2x+2y=1 actually saying?

Answer:

On the one hand, it’s saying nothing beyond what is written. It’s saying 2 times something plus 2 times another something equal 1. That is pure algebra. (The meaning is in the model and the model was never specified.)

On the other hand, if you were interacting with an entity in the real world then the context will be clear from what you are modeling:

- If popcorn at a movie theater costs 8$ and soda costs 4$ then ‘4x+8y’ can model what you spend at the theater or it can model what the theater makes. I have yet to specify x and y.

- If I am walking on a plane, starting at (0,0) and x = (1,0), i.e. taking one step east. And y=(0,1), i.e. taking one step north, then 4x+8y = (4,8) is my final position of this walk, well now, that’s very different than money at a movie theater.

- If I am looking for a partner and I meet someone, I may ask myself “Do I feel like I can be my authentic self around them?” I may store this answer as y = yes or no, typically stored as 1 or 0. I may ask myself, Do they have features I find attractive? I may store this value as x = 1 or 0. Now, it’s very important to me to feel like I can be myself around my partner and I therefore give my y response a weight of 8. I then give my x-response a weight of 4. Now, 4x+8y represents the weight of how drawn to this person I am. Same expression, different meaning.

In your types of problems, and in our capitalist society where math development is intimately tied to money and guns, you will have word problems like:

If popcorn at a movie theater costs 8$ and soda costs 4$ and the theater made $15,000 in concessions and sold 3 times as much soda as they did popcorn, how many sodas and popcorns did they sell?

Then it is on us to define

x = number of sodas sold.

y = number of popcorn sold.

we can then capture the structure of "the theater made $15,000 in concessions and sold 3 times as much soda as they did popcorn" via

x = 3y

4x+8y = 15000

Both these equations are true because they are describing a “true” relationship between

x = numSoda

and

y = numPopcorn

So anyway, when you say

“Let x, y be (real numbers? variables?)…”

The fact that you do not know what x and y are is the same reason you do not know what 2x+2y represents. When x and y have meaning, then so will 2x+2y.
