Dark Energy and Non-Conservative Forces
DLTherrien replied to DLTherrien's topic in Astronomy and Cosmology
Thanks. I will check it out. I am getting a better understanding of the math although the process is slow. I am a busy guy with work and school but Little by little I will get it. I find many people use the same math in their explanations so just by reading I am starting to understand it. I can see why it takes such intensive study. -

MIt's web site is very cool. You can essentially take any of their courses. Physics, Quantum mechanics etc. etc. -

Cool. I went looking for some more on this and I stumbled across this. This seems to be a good way for me to get started on the math and from MIT. What do you think? https://ocw.mit.edu/courses/mathematics/18-01sc-single-variable-calculus-fall-2010/1.-differentiation/ It appears to be all free. Cool. The link is the page where it all starts. It seems like all I will need to get up and running will be here. Not just some you-tube video. -

I wasn't sure really when I posted. Going by memory which was obviously flawed. Now though I have gotten some cool answers with good explanations of the math. How do we know the mass of an electron. Last time I checked, we cannot actually see one and looking as we all know is detrimental to the experiment so is it just the math that states that and how if so did we come up with that conclusion. I am about to finish "The Grand Design" tonight so perhaps it will answer that question for me. -

Just got home from work. I will look them over in more detail in a little while. I was at work when I first responded. Little time to be thorough. It is 4:04 PM here. Dinner time. -

That would be what is called h bar then? An h with a bar through the top.That is how I have seen it described. As far as the way I wrote it, I didn't copied from the web just to show how the variable h holds that information but thanks for the detailed explanations. They help anyway. Sorry for the huge image.. Just copied the first one I saw and pasted. The hbar is so we don;t have to write h divided by 2π, A shortcut because it is used so much is what I remember reading. Just notice you already mentioned H bar. Sorry. Little busy here at work still trying to beat the coming rain. -

I have an experiment of my own in mind where I will run it and leave it for a month or so and see the results. You just reminded me to pick up two identical time pieces. I'm not scared. I can figure out anything if I put my mind to it. One question I have before I really dive into the math meaning calculus and try to understand it is this. I am aware that the symbols used are just variables; that I am familiar with being a programmer; we use them all the time. Integer, Boolean, float etc,. I will use Plank's constant as an example of what I ask. It's value is 6.62607004 × 10-34 m2 kg / s ... copied from the web; which is supposed to be the smallest possible thing in our universe if I understand it correct. The variable .. h .. Still there are many more which all appear to be variables holding different values which makes sense because the values are difficult to write on their own. Same reason we use them in programming. Do you guys meaning math experts actually remember what they all mean or their values and if not how would you do calculations if you didn't? I hope you understand my question. @swansont,, @Marcus, @studiot and anyone else who reads this. -

And I believe then we go insane. That is why I find this so interesting. I have seen and experienced Newtonian physics. They are all around us and come naturally over time to the point they are routine and nondescript. I need things that stimulate my thinking. This definitely helps with that to the point I come up with all sort of craziness but that is the fun part. Once I learn the math which I will, then I can try to prove my insanity which will then make me better at the math and the cycle continues. .What else do you do at 49? Watch football, sit on the couch and complain? Not his guy. Knowledge for me is like a toy. Every time I learn something, I get a new version of my toy. And I greatly appreciate all of your support. You are very patient people. -

I am the type of person who gets easily bored with things. Once I get to the point I feel there is nothing more to learn, I move on. This is why I believe I am so drawn to this science. I will never run out of things to learn. -

I already get a lot of it and it makes sense although it should not but only because I do study the known facts as we see it. Definitely bizarre but it is what it is. Learning the math is something I aspire to and thanks for the book suggestion. That should help .I study in my spare time online but I have had to even revisit algebra. Been a long time so brushing up from there. -

Confucius says: "Man with watch always knows the time. Man with two watches is never sure." Confucius needed to lay off the pharmaceuticals. Walking around with two sundials on your wrist is just silly. As far as what you say about zoning in; that is my intention eventually.. -

That was a cool way for sure to explain it. I get the whole idea of space time though. Have for some time although I still have questions and doubts about some of the concept such as if time is also a wave, (Possible) how do we know we do not always interrupt the experiment by observing it like it or not and there is no way to come up with a different answer? What I want to know is everything else. My main interest although cosmology and astrology is also interesting is the Quantum world. Time and space for me is really just a side show to that. For that reason I find string theory a path that I am waiting for some answers to develop although it even in name and description will most likely change once something more is understood if ever. There might be a limit to what we will ever know about it. What can be observed directly through experiment might have its limits even at close range. Even before I started to study this stuff I always had the idea crazy as it sounds that the farther we look, we will always find more in our universe partly because it is created by us observing it. After reading a book which was a suggested path to take by others here instead of the internet which i immediately have found is better, and that book being Stephen Hawking's ... The Grand Design, I am learning I may not have been that far off in that theory or like Einstein liked to call it; a thought experiment. Deep I know but if we can truly change the past of a particle by observing it and particles can be seemingly anywhere and everywhere at the same time until observed, how do we know an entire planet or a star could not be formed in and instant by doing the same for countless particles at once just with a glance. There very well could be more to it when it comes to consciousness. Suddenly there is a billions of years old star out of no where because the past choices made by all of those particles at different times for all have just been changed and like the lottery, we have a winner! Are we capable of much more that we know and does it only apply to humans or does anything with a conscious mind also have the same innate or to stick with the favorite scientific synonym ... intrinsic abilities? If we were not here to observe it, would it really be here? My mind has been "lost in space" for a long time. I am interested for sure in the read. I am immediately finding as you and others have said that books are a better way to study and that will be my path for now on. The one I am reading now starts at the known beginning of science in general and by following that path it has made it far easier to understand how we got to the point we are now. Addicted. Couldn't put it down. Four hours sleep. Gonna be a long day at work. I am going to search Amazon for the titles you recommend and others I cannot find in stores. Only way I know of to find even used Physics books other than perhaps E-Bay which I do not trust. When at Barnes And Noble, I looked for the aisle trying to find books on Physics and not such a popular aisle. I had to ask. Tucked way back in the corner in the science section. When I asked, I got he look of "But Why?" -

Cool. Thanks I will check it out. I am about halfway through Hawking's The Grand Design. Just starting to get interesting. So, in 1966 they still believed in the aether? Even spell check doesn't believe in that Last ten or so lines of page 25. Most likely will have to order that online. Barnes And Noble didn't have the two you offered. Have to order them also. -

HUH? Don't try to elaborate. I will read up on it thanks.
