The funny thing is I was afraid of cars before I bought this qaraab car, I hate the idea of not knowing what I'm using, this eventually led me to investigate the basics of how a car functions with the intention of not getting into an accident or standing on the highway with a broken car.
I can do the basic, yes, I haven't replaced windshield wipers thou and I'll try to do the tire replacement when changing to summer tires.
I'm literally the farsame-yaqaan(next after my mom)of the house, everytime my aunt needs someone to fix her stuff, I'm the first one she calls, she doesn't even trust her man, she literally tells him that can't follow instructions and it is better for him to be in the kitchen, let's call Nalle for help before everything gets ruined,

I have had a finger in every pie as they say when it comes to assembling a lot of things in the house. Assembling IKEA furniture is the best thing ever, I don't get how people find it hard
Now that was a really interesting way to calculate the leaves of a tree

HeyI come to think of the other day I was wondering if the seasonal air quality changes during winter, especially in the northern hemisphere, isnät the air quality bad during autumn/winter considering there are not that many leaves around?Or does the Amazonian rainforest makeup for it?
I always get bad during winter, I really do think the problem is the air, my throat gets dry and particles get stuck in there. I don't know how to explain it, but I can really feel it, I know it sounds weird but I can suddenly start choking when I go outside and inhale deeply, I always have water with me in case I get attacked by the air.

I never have this issue during spring and summer. ( well I only suffer from pollen allergy during spring, but otherwise, it is all good)
Isn't it quite "impossible" to get the
weight of the earth in ton, kilo, gram? I think it is more appropriate to say the mass of the earth, since getting the exact weight of the earth is still a utopia.
As for the mass of the earth,Newtonäs law of gravitation says that a thing attracts another thing with a gravitational force which is proportional to its mass. And as you mentioned the two objects must be spherical in order to calculate the mass, you use the famous formula: F=GmM/r^2 . I think you already know this, I might have misunderstood your question thou.
And btw look up Cavendish experiment, and the issue with the big G, it is quite interesting. Despite the fact that many experiments have been performed for the past hundred years since Cavendish's laboratory determination of the gravitational constant G, the knowledge of G is comparatively poor, especially if one compares it to how far we have analyzed Planck's constant for instance, or other units.. Many scientists are trying to measure it, and the uncertainty of this unit is increasing rather than decreasing.

This is really fascinating wallhi, thinking of every single thing, human(and animal) beings that have lived on this earth is counted in the mass, even the deceased ones. we are all just a bunch of molecules getting recycled, one would think that the increase of population would mean the earth having heavier mass but that's not the case.
Makes sense when Ilahay will bring out all the living things from the graveyards, even when they have technically "disappeared, vanished", they are all still there.

Septillion, how good doesn't that sound saying it

Let's see how many zeros we'll get if we convert it into grams.
6 000.000.000.000.000.000.000.000.000. grams. That is basically billion billion billion grams of weight, damn it is so hard to comprehend. 6
octillion grams.
(in swedish it is kvadriljard, we use the long scale of the number naming system, it took me some time to get it right lol, septillion is 10^42 in the long scale and that is definitely not the right weight )
Damn guys, you have discussed so many things. Great to see the thread didnät die despite people going back to schools and whatnot. Me ish proud with chu. Keep discussing and enlightening the world, and as Carl Sagan said; "There are naive questions, tedious questions, ill-phrased questions, questions put after inadequate self-criticism. But every question is a cry to understand the world. There is no such thing as a dumb question"
@DR OSMAN you seem to be interested in space and astronomy, have you read Carl Sagan's Cosmos?
