No, how can I compare any two CPUs?

Hi, Back in the day, I remember my PC going from a x286 to a x386, to a x486, then pentium. It was fairly easy to compare the changes, it was easy to notice the clock speed that was increasing, from 33Mhz for the x386 to the 300Mhz for the pentium. In the recent years, we seem to be reaching...

cool, this is helpful, thank you

Thanks, I'm glad you see the linguistic muddle too :)

sounds like a nice article but I can't access it

yes, thanks for alleviating my fear :)

Hi, A little background before my question: I read that microwave oven frequencies are at 2.45 Ghz, or about a 12cm wavelength. Lately, 5G is using frequencies called millimeter waves, and these frequencies can be as high as 40Ghz. So, linguistically to me, it seems as microwave oven waves...

I got curious while I was doing it. Your and others answers on this post have helped me understand buoyancy better.

Wow yes, this really helps! The numbers make it easy to visualize and I'm about that weight. Thank you @JT Smith.

I heard of the eureka moment he had in the bath tub which was something like "The upward buoyant force is equal to the weight of the liquid displaced by the body."

I don't know, my BMI is 28 if that helps?

Hi, I was wondering, what is my apparent weight in water? For example, when I tiptoe on land, my calf muscles are pretty much lifting all my body weight. But if I were to tiptoe with just my head out of the water, how much weight would my calves be lifting? And as I move to shallower water, how...

For a friend, because of the impacts of the war, the drug is in short supply and she wants to source via alternative sources she but can't be sure of the quality.

Hey that's an interesting idea. If I have a real sample, and a "test" sample, then I wonder if I do a TLC, the chromatograms should be identical? Could that work?

If you had this chemical compound, for example, how could you test if its pure? $$C_{15}H_{11}I_4NO_4$$
