I wonder if any of the more scientifically minded people on here could help me, please.

Sacrilege.

Ha! Well spotted! I would buy you a beer for that if I could.

I have a few friends who teach in high school and 99% of the students know the player but not the philosopher (or better, used to know, as Socrates the player retired, and later passed away, a long time ago). Countless times I heard (and made) jokes about this.

On the connections between football and philosophy, how can we forget this classic?

I was the opposite way round. I'd heard of the philosopher but not the football player.

 

[mrzz]

O.K. pal. I knew there was a connection between them but forgot what it was.

I've never heard of him.

A picture is worth a thousand words, specially to help us remember. This one is worth one million words:

Plato and Aristotle are in the center. Plato is older, his finger pointing upwards makes reference to the role the ideas and ideal concepts had in his philosophy (were the "Platonic" comes from, I know you will like that), while Aristotle has his hand turned down, as his philosophy is much more "down to earth", to put it bluntly. Socrates is the big man in orange at the right of both (he does not look much older than Plato, actually a curious thing to check).

Thank you very much. I like mnemonics to help me remember too like "eat good bread dear Father" & space= F.A.C.E. in music reading & Richard of York gave battle in vain for colours of the spectrum. I did like that. It's a good piece of art too.

We do where I live. I guess that we could also use the term copulation to mean that too. Like I said before I was trying not to be rude & too explicit here by not using the term sexual reproduction.

I guess if you're understanding it or defining it under those terms that questions of morals would definitely come in as the people involved would be having an affair &/ using a brothel. However, like you stated early man didn't have the same values as they have today & may have been polygamous or even like animals. Don't forget! Marriage hasn't always been around. Before the advent of marriage, humans would have been as free as animals & able to cop off with anyone of the opposite gender they wanted like animals do in the wild. Who came up with the idea of marriage? An early human or early society. Marriage like many other things including religion is a social construction. They're not natural. We haven't always had them. Society brought them into being.

Thanks for that clarification. I'm obviously with you now & sorry for my rusty brain who could not grasp straight away the emotional meaning of your words. It'd be easier if I could look in your eyes rather than online searching for the meaning of your words. But I learned a fair bit in the process.

Very good deflection mrzz, with this classic. You earned your beer back from us, scientists & sport fans, for it.

You're welcome. To be honest, I learnt the word in conversation with someone a bit since rather than through reading or being taught properly so I could have just got the gist of what was said instead of the whole meaning. You've no need to be sorry. It's me that has a rusty brain as I left high school 20 years ago & am talking about things that I haven't looked at since then or if I have I've just had the odd look. Some of the things I've been talking about I haven't spoken about since middle school which I left 25 years ago like Socrates. I've got a wondering eye so you would find it easier if you could hear my voice. I'm glad you learnt something.

Hope we all got the chance to collect those beers one fine day.

That sounds like it would be an interesting meeting. Since you'd all be boozing, you'd need someone sober to entertain. As I don't like beer only sweet wines, cocktails, mixed spirits & straight pernod, peach schnapps & Malibu & can sing I guess I could work for you all on stage. Lol. Speaking about drink, I'm very sorry I've been a bit off it the last couple of days but I went to a party & had a few too many vodka & orange juices so was nursing a hangover. Dad bought me a drink but instead of vodka & orange juice he bought me straight vodka & I had to go back to the bar for the orange juice & mix my own.

1. Why does Mars look red?
2. Why does Saturn have a ring around it?

 

[Chris Koziarz]

1. Why does Mars look red?
2. Why does Saturn have a ring around it?

The shallow responses are very simple.
1. Mars has red sand on its surface and very little atmosphere to obstruct the view. Other planets have thick atmospheres (Venus) or are gaseous (Saturn Jupiter).
2. Satellites of Saturn have exploded into tiny pieces and pieces orbit it as rings. Likely as many satellites as rings, otherwise why would there be separate sets of debris from a single satellite explosion?

Why is blood pressure measured in systolic over diastolic pressure in mm of mercury? What has Mercury got to do with it? I know old thermometer's used to contain mercury in order to tell the temperature.

 

[Horsa]

Going back to Chris's answer about Saturn's rings, how did Saturn's satellites explode in order to become rings?

 

[Horsa]

How does the puffer test detect the pressure in someone's eyes & going on from that how does that tell opticians whether people have glaucoma or not?

We used to measure air pressure in mmHg also. It is 760 mmHg. That equal 101.3kPa. That's the hight of the Hg column the air pressure can hold. And has nothing to do with T measurement in Hg thermometers (where expansion of Hg takes place as T rises).
You've seen BP measuring instrument: with a pipe where Hg indeed rises to 12-15cm when measuring a diastolic pressure of 120-150. You could scale it in KPa. I don't know why docs still stick to the old units, ask them, and even tell them from me that their conservatism looks silly when the rest of the world has moved to Pascals for quite a while now.

I don't remember to ever have learned trhat.

Going back to Chris's answer about Saturn's rings, how did Saturn's satellites explode in order to become rings?

It happened few My ago. Cassini (space robot) discovered before its death last year that the rings are that old. Saturn gavitational pull broke its moon into ice pieces and swallowed the core while icy pieces scattered on the orbit. Now they say it was just 1 moon, and the gaps between rings (such as main Cassini Division) are result or a later passage of other moons/large comets through the ring planes which sucked up some of the debris. The original rings used to be complete (without gaps) and bigger.
The rings will eventually disappear given enough time, by a friction of Saturn's "exosphere". The friction drag slows down the debris closest to the planet and the debris will fall. Just like man-made satelites' orbits decay overtime due to thermosphere/exosphere drag and fall down. The ring orbits are larger where there are less atmospheric gas molecules so the orbit decaying process takes much longer (100s My). The outer rings will disperse due to interference with outer moons.

 

[Chris Koziarz]

I found a latest info about many new papers that just came out, analysing the data Cassini gathered between Saturn and the inner rings:
https://www.space.com/42022-cassini-saturn-finale-ring-rain-surprises.html
Before said data, Saturn scientists thought exactly the same I was thinking (if I can brag about it) that the "ring rain"on Saturn due to the friction with thermo/exo-sphere be minuscule. But Cassini measured it to be much bigger: a decay that would result in all rings to fall off in just few Ky. So, if Cassini numbers are right, something must feed the material back to the rings, i.e. the rings must be a "living thing". Needless to say, Cassini analysed the rain consists of not just water ice, but other material, even including traces of "organic matter"! The latter is so unbelievable that sound like april's fool. We need to wait for the confirmation. Cassini also dicovered unusual magnetic activities due to the surface storms. All fascinating but I have not enough time to digest everything...
