Noticed that only top award winners got pictures of them with their projects is that like a requirment? Don't think I got any pics on judging day

Hello everyone,

Any tips for the ISEF college fair, I never had one at school let alone ISEF not sure if there are advantages other than getting to know more about the uni/scholarship program.

Thanks

Hello everyone,

I am currently a high school student trying to study the CKM matrix. I came across these equations but cannot find resources or any way to understand these equations (possibly due to their complexity but also due to the fact that available resources confuse me along the way).

Anyways, any help would be appreciated. I am not looking for a deep understanding of them since I feel like I do not know many of the fundamental topics to understand this but would love learn more about it!

Differential decay rate equation:  \frac{dΓ}{dq^2} ∝ G_F^2|V_{ub}|^2\lambda^{3/2}(q^2)|f+(q^2)|^2

(I am unable to put the non-latex version of this)

Lund's model: \lambda_s = \frac{P(s\bar{s})}{P(u\bar{u})}

\Delta\langle NK_{\pm} \rangle \approx \frac{1}{\lambda_s} - 1

Hello,

Just wanted to ask this question since I have seen many projects on ISEF say they are around 50% or even 600% improvement from older models or methods. For my project I did something similar but I got around a 9% improvement which is big in my domain but not as big as other projects which is making me worry.

I am not sure if they do relative improvements which inflates the percentage?

Thanks in advacne
