In Spivak's Calculus, he provides a """rigorous construction""" of the ordered pair.

To do so, he defines (a,b) as {{a},{a,b}}.

Can one of you explain how this is significant or rigorous. The definition and accompanying theorem seem arbitrary to me.

>Can one of you explain how this is significant or rigorous.
He is showing that if you have 2 ordered pairs which are equal to each other they are made up out of the same members, it is written right there on the page.
It is obviously important to prove this, else the definition wouldn't make much sense.

>rigorous
It obviously is rigorous, there are no uncertainties and the definition is clear and unambiguous.

>significant
You need ordered pairs to construct the rational numbers and other things but the necessity for such a thing should be obvious.

A lot of experts say people don't believe in climate change because it's something different and unassuming that people can't relate to and is difficult to observe with your own eyes.

I and most of the people I know HAVE seen it with our own eyes and firmly believe in it because of this.

Has anyone else here observed climate change for themselves?

A few warm years are not proof of climate change. That mentality is a dangerous one to have and can discredit actual climate change. Once you get a couple cold years, everyone's going to laugh in your face. Don't point to personal observations as proof, ever.

>>8958224
>Certain crops literally taste worse
I've recently noticed a lot of vegetables taste much sweeter than they used to. Is this just due to selective cultivation or is it climate change? E.g. carrots taste sickly sweet nowadays.

>>8958239
no it is due to GMOs

"Each nucleotide is composed of one of four nitrogen-containing nucleobases — cytosine (C), guanine (G), adenine (A), or thymine (T)."
>>
Although there are 4 nucleobases, these really function as a binary system since they come in pairs, with cytosine always binding to thymine and guanine binding to adenine.

What does /sci/ think of the study of consciousness through psychedelic drugs?

Is Is Terence Mckenna ascended theorist or complete pseudoscience?

The problem for me is that none of his big claims are really testable.

However I think his subjective experience in the study of the psychedelic experience is very useful.

I've listened to the entirety of every McKenna lecture I could find online.

The mans intellect was vast. But I would primarily characterize him as an experimental philosopher. In that he was exploring the boundaries of consciousnesses through psychedelic drugs.

pseudo for sure. He might have been smart and intellectual, but it was all pseudo at best

I was just thinking today, about how he said in Cosmos that human beings evolved because of domesticated dogs.

Its a clever idea, but, does he have any empirical reason to believe it? What really got my buttons boiling, was, doesnt that imply that there are genetic behavioral differences between human populations? After all, not all peoples had dogs. The direct implication is that there are genetic differences in human psychology. He would never admit that!

What's the problem with this? Sounds like people are just mad jealous they're putting in tons of effort and still get mediocre grades.
I ace everything I ever try for, but I rather do fun things than boring things like studying.

>>8957914
Most people believe they're more intelligent than average. "Smart but lazy" is something you hear from idiots who want to be treated like they're better than average while having nothing to show for it.

Such a small number of people are actually capable of putting in significant consistent effort that those who do have a good chance of standing out, even if they don't have a "natural" advantage. It's far better to have discipline and ethic than to just be "smart". But then you get shitheads who never tried a day in their life acting like they're better than most people just because they got okay grades in high school "without trying".

Does anyone have any advice for studying or paying attention in class for someone with what is medically known as ADHD?All through middle and high school I can remember studying maybe once or twice and I never payed attention in class. I hate the medicine they prescribe but I'm a little worried going into college that I won't be able to perform as well as I'd like.
NOTE: Whether or not ADHD actually exists is irrelevant to my question.

Birth rates are falling.

If you think overpopulation is a problem then you've never taken a roadtrip across the US. 90% of this country is virtually uninhabited and most of it isn't even farmland. People just have this derangement where they think they need to pack themselves into big cities and then cry about overpopulation.
