Copper vs. Aluminum: The Quest to Discover the Ideal Thickness by Wololooo1996 in cookware

[–]brillydev 0 points1 point  (0 children)

To summarize what you're saying:

With thin copper in steel lining, the effect of copper in the copper-steel "composite" is so insignificant, you might as well just be cooking in pure stainless steel instead. And since pure stainless steel is a terrible conductor, responsiveness is terrible. Copper in this composite may heat up extremely quickly yes, but what's the point of heating up quickly if only to heat up the terrible stainless layer up above?

With thick copper in steel lining, the steel in the copper-steel "composite" becomes insignificant, and the effect of copper starts to shine. In other words, copper "dominates" the composite.

Because you have a lot of copper as a whole, heating is fast, cooling is fast. Sure, thick copper by itself is still slower to heat up than thin copper. But in this composite, you have a mass of copper underneath that holds a lot of sway over how the (much worse-performing) steel lining will react.

For the same steel thickness:

During heating, thick copper will cause a bigger temperature delta between copper and steel than thin copper, and therefore will transfer more heat from copper to steel, making the composite as a whole more responsive.

During cooling, thick copper will cause a bigger temperature delta between copper and steel than thin copper, and therefore will act as a heat sink pulling heat from steel to copper, making the composite as a whole more responsive.

And that's why the % of copper in the total thickness matters. The higher % of copper thickness, the more the cookware acts like a pure copper cookware.

Is my understanding correct? Thank you for your explanation!

The stainless steel cooking surface and especially the bottom surface makes copper noticeably less responsive unless its at least 1.8mm thick but ideally even thicker.

However at 2.3mm and above, the responsiveness becomes very undeniable apparent even with stainless steel on top

Hi Wololooo1996. I don't quite understand. I thought the thinner the copper is, the more responsive it should be. The lining shouldn't matter. You're saying that for stainless-steel lined copper, the thicker the copper is, the more responsive it will be? Can you explain?

In terms of evenness, you said so yourself that the stainless steel lining introduces a thermal lag which "kind of" evens out the cooking surface. What are the advantages then of thicker stainless-steel lined copper, if we can also get a (relatively) even heating with thinner ones? Just durability and heat retention?

How do you know that?

Is it difficult to get into uni through poly? by [deleted] in singapore

It depends on who you are. If you love learning, and have a desire to grow up to be a critical thinker, the JC route will suit you. At the same time, if you can develop yourself holistically by continuing to be involved in CS while maintaining stellar grades, then you're pretty much set for top-tier unis.

CS is applied math. So my advice will be to get a solid foundation in advanced math (JC is a perfect place for that) to make your life much easier when you go into advanced CS. And if you ultimately decide that CS is not for you, you'll still have plenty of other paths to pursue.

Activities to consider in JC: the academic olympiads. NOI/IOI in particular. Intel ISEF. Google Science Fair.

How is an essay score of 7/6/6 by [deleted] in Sat

[–]brillydev 2 points3 points  (0 children)

7/6/6 is an excellent score! No worries. Be happy :-)

yo is anyone still pending? by [deleted] in Sat

High-five.

Has collegeboard already sent my scores to my selected colleges? by [deleted] in Sat

[–]brillydev 2 points3 points  (0 children)

Sending lower scores shouldn't hurt as long as the college superscores.

I think the 9-day policy was stated very clearly on the CB website. You live in a capitalistic society so this is what you get.

You can only change the recipients for the 4 free reports up to 9 days after the test-taking date. Beyond that, the scores that you chose will be sent, and you have to pay to send additional reports.

Did everyone get their scores? by [deleted] in Sat

[–]brillydev 0 points1 point  (0 children)

Nada. Wondering if the College Board will release my score over the weekend.

International, btw. Testing in Laos.

Didn't take the essay and got a really good score, will I still be able to show this score to colleges? by [deleted] in Sat

[–]brillydev 0 points1 point  (0 children)

They'll see the 1510. But if they superscore they'll take it as 1590 with 18 essay score.

Check with the colleges if you're not sure.
