  • that putting the thermostat up higher will heat the house up quicker (edit: I have in mind a bog standard UK home thermostat)

  • that sugary sweets make kids act "hyper"

  • that the moon's apparent size is due to how close it is to earth (same for seasons and the sun)

  • that your base metabolic rate slows as you age and is primarily responsible for you putting weight on in middle age

Explain?

Also, what's the size/proximity of seasons?

[–] FourPacketsOfPeanuts@lemmy.world 1 points 12 hours ago* (last edited 12 hours ago) (1 children)

The visual difference of the minimoon and supermoon is not that great, see here but hold your phone at arms length. This is the maximum difference (taken 6 months apart) that the moon ever is relative to itself. In practice, from one night to the next or one month to the next the difference is barely noticeable.

When people say "the moon was huge tonight" what they are generally seeing is the moon illusion

The reference to seasons is badly worded, but what I was referring to is that the earths seasons have nothing to do with how close to the sun it is

[–] howrar@lemmy.ca 2 points 10 hours ago

Ah, I didn't realize the moon could look bigger/smaller at different times. I thought you were saying that the moon is actually the same size as the sun or something like that.

[–] comfy@lemmy.ml 2 points 15 hours ago

Huh, these are all common sense statements I would have assumed true. Four our of four, good work!

In the case of inverter air conditioning it might make a small difference at it won't throttle down as it approaches the intended, not commanded, target.

If you have a 2 stage furnace, this may actually be a thing.

that your base metabolic rate slows as you age and is primarily responsible for you putting weight on in middle age

Is this not true?

No. At least, it's not the general cause of 'middle age spread'.

The base metabolic rate refers to how your individual cells respire when at rest. And a brain cell in 20 year old respires much the same way as a brain cell in a 45 year old. Same for all other organs. There is a gradual decline but it's on the order a single percents.

Organs and tissue at rest respire at different rates, so some of the change people notice is due to change in body composition. Muscle at rest burns twice the calories as fat however this is still only a minor contribution.

Base metabolic rate doesn't vary much at all. The vast difference in daily calories consumed as one ages is general activity level.

Overall metabolic rate = base rate (varies a little on body composition) + calories burned in general activity (varies a lot)

People typically are less active between 20 and 40. This is not just sport but also lifestyle. People become more efficient in their habits as they age. They drive instead of biking or walking. They sit in the sun on holiday with nice food and wine rather than dancing all night. Etc

Lifestyle choice is the primary cause of excess calorie intake and 'middle age spread'. Not "my metabolism that I can't do anything about".

Same with electric range/ovens.

[–] tko@tkohhh.social 2 points 18 hours ago* (last edited 18 hours ago) (1 children)

Is this true?? I always assumed that electric ranges simply had a variable duty cycle controlled by the knob. That would mean that if you want to get a pot up to a specific temperature, the fastest way is to set the knob to high until you reach the temperature, then reduce the knob to the desired temperature.

This is different from how an HVAC works, where you set an actual temperature and the HVAC runs until that temperature is reached.

But I could be totally wrong about how electric ranges work.

[–] AbouBenAdhem@lemmy.world 3 points 18 hours ago* (last edited 12 hours ago) (1 children)

I tested mine with an infrared thermometer: Starting cold, I turned one burner to medium and another to high, and measured them as they heated up. They heated at the same rate until the medium burner reached its target temperature.

[–] tko@tkohhh.social 2 points 16 hours ago

Interesting... if that's true, then you can know what temperature each setting on the knob is.

I wonder if this is true for all electric ranges?

  • that sugary sweets make kids act "hyper"

Do you happen to have a source for that? Coz I have witnessed kids act like a horde of wild monkeys on crack right after eating dessert on multiple occasions.

[–] FourPacketsOfPeanuts@lemmy.world 12 points 23 hours ago (2 children)

I listed it because it's one of the things I would sworn by too having seen it first hand. However when you conduct a double blind experiment, kids still get excited at parties / treats / days out / when their friends are over when there's no sugar in the treats.

https://www.medicalnewstoday.com/articles/medical-myths-does-sugar-make-children-hyperactive

In otherwords as parents we massively underestimate how excited or crazy kids can get just because they're excited and not because of something in their bloodstream..

[–] tomi000@lemmy.world 1 points 10 hours ago (1 children)

That may be the case. I will need to conduct my own research^^

Make sure it's a blind test ;)

[–] ArcticPrincess@lemmy.ml -4 points 22 hours ago (1 children)

The claim and evidence here are not logically consistent.

It's like saying "cyanide won't make you dead" because, look "people still get dead from falling and crocodiles, even if there's no cyanide around".

[–] FourPacketsOfPeanuts@lemmy.world 9 points 22 hours ago* (last edited 17 hours ago)

no, it's not. it's a meta analysis of multiple double blind studies. multiple

β€œFor the children described as sugar-sensitive, there were no significant differences among the three diets in any of 39 behavioral and cognitive variables. For the preschool children, only 4 of the 31 measures differed significantly among the three diets, and there was no consistent pattern in the differences that were observed.”

if you did the same with cyanide you would be able to conclude that "taking cyanide and being dead is positively correlated" even if there were other causes of death. in this wide summary of multiple double blind experiements, there is no correlation between sugar intake and child behaviour. that's not to say kids don't act up and get hyper, but it's other causes, most signficantly parents just underestimate how hard kids find it to regulate themselves when having treats of any sort (non-sugar included) or being in a party atmosphere with friends.
