Articles I maintain
Jurij Moskvitin Jurij was a personal friend of mine

My general contributions


I added a comment about visibility when X-rays ionize air

I have boldly added illustrations and references to the article about Closed-eye hallucination

I have given the magnetopause article a huge overhaul, adding an home made illustration, a table of the solar planets magnetopauses and even stated an equation :-)

uploaded a video of a cloud chamber in action

Added a lot of info about Jens Martin Knudsen

Gluckstern's formula

 * $$\frac{\sigma_{P_\bot}}{P_\bot} = \sqrt{ \frac{720} {(N+4)}} \frac{\sigma_{xP_\bot}}{0.3 B L^2}$$

Solving for $$\sigma_{x}P\bot$$ gives


 * $$\sigma_{x}P_\bot=0.3 \frac{ B L^2 \frac{\sigma_{P_\bot}}{P_\bot}}{\sqrt{ \frac{720} {(N+4)}}}

$$

Inserting values for BaBar $$B=1.5T$$, $$L=0.8m$$, $$\sigma_{P_\bot}=0.3%$$ and  $$N=40$$ layers gives an estimated precision of


 * $$ \sigma_{x}P_\bot=0.3 \cdot \frac{ 1.5 \cdot 0.8^2 \cdot (0.3\times 10^{-3})}{\sqrt{ \frac{720}{(44)}}}\frac{1}{P_\bot}=\frac{213\mu m }{P_\bot}$$

At a transverse momentum $$(P_\bot)=1GeV/c$$ this is simply $$213\mu m$$

Resolution function

 * $$(\frac{\sigma_e}{E})^2=(\frac{K_1}{\sqrt{E}})^2+(\frac{K_2}{E})^2+K_3^2\Rightarrow$$


 * $$\frac{\sigma_e}{E}=\sqrt{(\frac{K_1}{\sqrt{E}})^2+(\frac{K_2}{E})^2+K_3^2}$$
