Currently taking AP Biology and AP Chemistry at my high school so I have a decent general knowledge of both subjects. I understand some aspects of psychology too.
I want to study chemistry in college so that's what I'm most interested in discussing. This has potential to be a good thread. There's a lot to discuss on science-related news. |

I took AP Biology, AP Chemistry, AP Calculus, and AP Physics in high school. (I earned a 4/5 on the Physics exam but earned the full 5 on the others.)
I took upper level physics and calculus classes in freshman year of college. In my sophomore year, I took statistics and psychology. I've had an interest in marine biology, zoology, astronomy, and paleontology for all my life if that's worth anything. |

Actually, speaking of astronomy and biology, a fellow colleague of mine recently took an interest in astrobiology and the whole idea of being able to engineer plants that could grow on Mars. It's something I thought sounded cool. |

I don't really actively study any natural sciences aside from one last required chemistry class I'm taking this semester (I had enough credits from high school APs to get out of most required natural science classes). It's not so much that I don't think they're interesting (well, aside from Biology which simply doesn't interest me at all) as much as it is the fact that I'd rather devote my studies to other topics. As such, I have an interest in them as a casual observer, so perhaps I'll find some discussion here interesting.
oh and i'm majoring in cs so maybe i'd be willing to talk about computer science too though i generally don't find discussions on that topic to be something i enjoy much, but maybe someone will be able to change my mind. who knows. |

I love science but i dont like the classes my school offers for the subject. I took an astronomy class expecting to talk about how cool space is but it ended up being primarily learning how to measure very very long distances for 12 weeks.

I am currently studying computer science. This means learning about programming/software development as well as hardware and telecommunications, all of them requiring maths. In fact, for the first two semesters 4/10 lessons are maths.
Greece has a different education system. For the last two years in high school, we are required to choose one of three directions, theoretical, exact sciences and applied sciences. I chose exact sciences for my second year but switched to applied sciences for my last. This means I learned calculus and integrals, classical physics(Newton, thermodynamics etc.), non organic chemistry as well as basic programming and this sh**** lesson called bussiness management. Aside from directions, the lessons everyone has to have include all sciences, at a more basic level. From all these I used to love chemistry and later learned to love physics. I always loved programming, from the first time I tried it in my last year in junior high school. |

I'm in my last semester of undergrad to get my b.s. in economics. Economics is the mathematical (and statistical) representation of human behavior. It's a social science and there are two encompassing branches: microeconomics which is the study of individuals with unlimited desires reacting to their constraints and macroeconomics which talks about the overarching economy in general terms (inflation, nation's output, currency valuation, etc.). Mainstream economists try to verify their theories through statistical analysis of real world data (i.e. econometrics).
I could talk about things that are relevant to political discussions in the US, like why the CBO's analysis on the minimum wage's affect on employment doesn't fit with the consensus of labor economists, why the Council of Economic Adviser's reasoning in their response to the CBO is flawed and the actual logic behind those labor economists' conclusions which ties into the dual purpose of the minimum wage. But I hate politics. I could also talk about random stuff like the economics of dating which is more interesting. I wasn't a big fan of economics when I first started studying it because the principles and intermediate courses were completely abstract. It wasn't until I started studying the applied uses, namely Game Theory, that I got into it. I took/am taking a bunch of electives because of that; besides Game Theory there's: Economic US History, Money and Banking, International Trade, International Finance, Economic Demography, Industrial Organization and Labor Economics. If you want to know more about economic theory, I'd suggest reading academic textbooks first and not random books or news articles written by non-economists... or Austrians. If you want to know more about the US's past, A New Economic View of American History is interesting, cheap and you don't have to know much theory to understand it.

I don't know about politics, but economics is often associated with money (which I suppose can go back to politics) from my experience. What's often undermined or forgotten is that economics, as nasic870 pointed out, is a study of how we decide to make use of available resources.

But usually I see it associated with politics or business and not as it's own standalone subject just because economic decisions have significant implications in those areas. Some schools reinforce that idea by combining their business schools with their econ department and economics is a specialization in undergrad and grad business degrees. Not to mention the entire financial industry's instrument pricing models like Black-Scholes are based on financial economics. Generally, economists want to measure welfare of countries and their citizens. On an individual level, they want to measure utility - happiness. They can't observe that though. There's something called a happiness index but, I don't know, it looks like non-sense to me. So money, GDP per capita, etc. are economists' best guesses and most easily measured proxies for utility which is why they use money as a quantifier.

How do you feel about the economic element of environmental science? Has this type of question ever come up to you? |
|
||||
![]()
Yeah, it came up when I was studying the environmental Kuznets curve - the idea that environmental degradation increases as an economy first grows (usually in the takeoff/manufacturing stage of development) and then decreases as the economy fully matures with new/better tech available and more emphasis placed on environmental policies in those developed countries (which are service driven economies).
And there's proof of that being true for some mobile (air and water) pollutants, e.g. Krueger and Grossman's Economic Growth and the Environment and that local economies start caring more about their local environment as their per capita incomes increase: my college is taking out parking lots to reforest the area to reduce the chance of flash floods. But not for every pollutant like green house gas emissions. And the environmental Kuznets curve doesn't take into account that some actions have irreversible damage but I wouldn't know what's irreversible and what isn't besides depletion of non-renewable resources. Economists in the UK made a compilation report that's not technical . I haven't read through most of it. Dasgupta also compiled a book on this, The Economics of Non-convex Ecosystems but it's very technical, meant for Ph.D's to read. There's also some literature on international trade's effect on the environment - iirc, their conclusions were that trade didn't affect degradation anymore so than home production/consumption. Policy wise, a high tax on carbon emissions and large subsidies on R&D would probably address the issue of climate change for regulated markets. But, like Lomborg pointed out, it might be more costly than it's worth at the moment. It probably wouldn't be an equal money transfer from taxes to subsidies. Oh, and there are some theories about limits of economic growth because of limits of resources and empirical work on how those limits affect prices. I haven't read into those, though.

All the math and calculations is needed if you want to develop these theories. Or, in general it is. Michael Faraday is a very good example of a very good physicist whose knowledge of math wasn't very much. Trigonometry was about the most advanced math he knew, and most physicists have a strong grasp of calculus. Faraday is an exception to the rule though, not the actual rule. I am an astronomy major, who is going to take a lot of physics. I have taken the introductory calculus based physics (my High school had no AP credits so I had to wait until college to do this) and a class on Special Relativity. I will be doing 300 and 400 level physics classes next semester. As for astronomy, there are only 5 required courses, and I am doing one this semester and the next 4 next year.

If the universe ever reaches maximum entropy, would the distribution of elements be similar to what it was after the Big Bang (mostly hydrogen-1) since anything heavier would have order that could be broken down? I've read that even protons might be able to decay so it seems like the universe wouldn't fully reach maximum entropy until everything had been converted to the most basic elementary particles.

You know, I don't think I ever had a huge fascination with subatomic particles aside from electrons. I remember my physics professor would sometimes go on tangents about his research on the neutrino, and half the time I would be thinking to myself: "Okay... cool"

Related: I remember reading somewhere about how quantum mechanics might deal with retrocausality.
It's hard to explain but to put it simply, this current present causes a specific past to exist as well the other way around. This discussion > invention of the internet > evolution of humans > formation of Earth > matter arises in greater quantities than antimatter > big bang It crosses over into philosophy at that point but it's just something interesting to think about. |

Somewhat science related, this site lets you browse through shortwave radio frequencies. Pretty fun to play around with and I've already found some interesting stuff.

Also that reminded me of something a science teacher a few years ago told me. We were learning about the ear, and the teacher played this recording of various frequencies of sound. Every time it changed, she would have everyone raise their hand to see if they could still hear it. However, her hand went down two changes before the rest of the class, which she explained was because of her older ears. Apparently some crafty people used frequencies above the range of older people as ringtones to avoid teachers. Found it pretty neat.

Not sure if I've shared this before...
BLACKFISH Blackfish is a documentary focusing on Tilikum- a large bull orca that has been involved in 3 deaths so far. SeaWorld has recently reported a 13% drop in attendance. And senators in New York and California have proposed legislation to ban orcas in captivity. Orcas will always be one of my favorite animals so I knew since I was a child that orcas didn't do well in captivity but it wasn't until I watched Blackfish that I realized it was THIS BAD. The film has an agenda (obviously) but the information on orcas is for the most accurate. If you can't watch the film, here are some facts: -Orcas in captivity typically only live 25-30 years at the most. In the wild, orcas have a lifespan of 50-60 years (male) and 70-80 years (female). -Female whales are artificially inseminated as young as 7 in captivity. Wild orcas typically start breeding at around 15. (Many calves end up stillborn or dying shortly after birth.) -Almost all male (and some female) captive orcas exhibit a physical deformity known as dorsal collapse. This occurs very rarely in the wild (~1%). -Orcas have complex matriarchal societies and children remain with the mother for all of their lives. Seaworld mixes orcas with different dialects and separates young from their mothers. -Finally, concrete tanks are simply too small and devoid of stimulation to fit the needs of an intelligent and highly active animal like an orca. Blackfish covers more on how SeaWorld endangers their trainers and some of their unethical, illegal practices. |

Finally, now is my chance to SHINE!!!!
I don't mean to frighten any of you, but I actually have a B.S. in Chemistry (and a minor in Biology if that matters). I am currently in graduate school and am getting my graduate degree (hopefully) in Organic Chemistry. I honestly love Organic Chemistry (mechanisms, spectroscopy, all that jazz) but I also enjoyed Biochem and most of the other chemistry subjects. Screw Chirality though, I hate that ****.

As a follow-up to my previous post, I did end up watching the film during a Friday night seminar, presented by some of the marine biology department. The film, itself is very powerful, appealing a lot to pathos. Kinvara's post of facts is very much deeply enriched with emotion to a point that it leaves you (or at least myself) in a trance where you believe everything about captive orcas is wrong.
Much to my surprise, however, the professors leading the seminar actually defended the use of captive orcas. One of them was actually a killer whale trainer in her youth and had said that there are benefits to keeping the orcas already in captivity. I think the first question brought up was whether or not the captured orcas were of any benefit to us, and the first reply was that they were easier to study - Which I can pretty much accept. Only a few students seemed opposed to the idea and had brought up releasing them (something I'm not completely confident in), stating that we've reached a point in time where we can continue imbuing a sense of wonder and desire to learn more about marine life without the use of the parks. In any case, it was a neat experience |
|

I'm sort of split on the issue, because there's not necessarily a guarantee whether the Orcas will lead a better life in the ocean, or whether they will succumb to such things as whalers, manmade trash/radiation, or natural predators. However, I do feel that if society is to contain them, we should provide better living conditions.

One of the questions brought up was whether or not SeaWorld could do better in their care and maintenance of the captive orcas. Is the only real option to release or kill off those already captive? |

This would be like studying people in a mental hospital or prison to make conclusions about the psychological behavior of the entire human population. (see Sigmund Freud) I honestly don't think there is a feasible way to care for captive orcas properly. They are simply far too large and to provide them with an enclosure large enough for them to get appropriate exercise would be ridiculously expensive. Ideally, the orcas currently in captivity could be placed in sea pens for the remainder of their lives. Many of the captive orcas are far too sickly to survive long in the wild but some of the wild-caught orcas might be able to be reunited with their old pods. |

Yeah, I asked the question because I don't really know much about them to make a statement about it. I kind of treated them like lab rats, in that they're bred for a specific purpose, but for whatever reason I forgot orcas and rats are very different.
Ironically though many of the students present were interested in marine biology because of SeaWorld. Wish some of them could have added more to the conversation |

Here's an article, whose topic is periodically discussed in my little circle of pre-scientists:
Nobel Winner Declares Boycott of Top Science Journals Don't pay too much attention on the boycott part, but instead on the basis behind the boycott - Nature, Cell, and Science act as gateway for scientists wishing to make a career out of their work. Since they are the top tier of journals, getting published by them earns you instant credibility. The problem is that all three journals possess specific limiting guidelines which force authors to compromise their written work. Another problem is the limited amount of space the journals possess for new articles, thus a screening process takes place to filter out what the editors believe to be "less important." Overall, the publication process almost promotes the publication of flashy articles - Subjects meant to make waves, and as such a lot of science is disregarded. Anyone here look up articles on databases? |

It's a shame that almost everything produced by the media consists of one of these errors. I wish we as a society chose to learn the truths of the world instead of focusing on whom murdered who today.

The media works much like the journals Nature, Cell, and Science I mentioned in my previous post, only the limitations inherent with the television medium are even more restrictive. I recall watching a "debate" between Bill Nye and another individual on evolution on one of the major television news outlets, and due to the nature of the medium, Bill couldn't really say a lot. In the end, I think it's really up to the audience to do the research themselves - The resources are made available |

I actually just checked out eLife just now to make sure there were no cost barriers and found an article that interested me. Turns out it's free to the public, which is also good. Schekman doesn't quite go over the disadvantages of other journals which include pay-walls and unrevised papers.
In regards to the general fact-checking part, it's something we just have to deal with. I'm in a party that believes that scientists who do the research should be the ones to convey what they've learned to the general public. I guess, however, that they are unable to communicate their knowledge well and so some middle-man interpreter is usually the one to do it. In an effort to mitigate this issue, we do have scientific communicators like Neil deGrasse Tyson going out to make sure that this knowledge isn't being completely distorted. |

Neil deGrasse Tyson on racism
A short video on Neil deGrasse Tyson speaking about race/gender when it comes to scientific community. While science itself is neutral, the institutions that make up the community don't exist in a bubble and have a long history of white supremacy and other forms of bigotry. Racists centuries ago (and today even) have attempted to "prove" that other races are inherently inferior. Bigots attempting to "cure" homosexuals by labeling their sexuality as a mental illness. Abuse of the mentally ill using lobotomies and shock therapy. Bigots should have absolutely no place in our scientific institutions but there hasn't been nearly enough effort into calling them out. |
