My stomach is slightly darker on the left half and does a strange dip going towards my sid before fading in. I'm only 16 and I've had it for a few years but have no idea what it is.

I've noticed my tex stuff is overcramped when displayed, these days so I'm finding out how to make it bigger. [math]{P_{n = 3}} = \left\{ {1 - {{\left( {\frac{5}{6}} \right)}^3}} \right\} = \left\{ {1 - \left( {\frac{{125}}{{216}}} \right)} \right\} = \frac{{91}}{{216}}[/math] It comes out bigger on my TEX editor, but is cut back here Any suggestions?

Typing f(x) = 0 within the LaTeX brackets produces \( f(x) = 0\) whereas typing f(x) := 0 leads to \( f(x) := 0.\) Is that something fixable, or one just has to be aware of it?

I see you changed over to a new LaTeX system, so just testing this here... \[y(x)=\int xdx \] \[\displaystyle{R_{\mu \nu } -\frac{1}{2} g_{\mu \nu } R=\kappa T_{\mu \nu }}\]

I think the following ideas 1.Solving global warming through undersea factories 2.Using the Kyoto Protocol to solve the US China Trade war While only sketched out as an idea here, can be verified as used to genuinely make waves across he science and political sphere on the global stage. Now then, those are my ideas the ideas of a layman. Here, around me, we have reputed scientists, pHD holders which is great. I invite you to work with me on developing those ideas above, and help me change the world.

Hello, My daughter is an absolute doll. But she doesnt speak, yet knows basic sign language. My concerns are she hits herself hard in the head when she doesnt get her way. Of course i tell her 'I dont hit you so, I dont want you to hit you' while trying to also stop her from constantly raiding our food cabinets. The teachers used food as a reward system and basically trained her to be a dog. By the time i figured that out the damage was done. How do i stop her from hitting herself? Any suggestions? Kristi

It could begin more gradually as you become a caregiver to an ailing family member, or as you step away from a longtime career. It could start suddenly with the separation or divorce or death of a spouse, or a fall that leaves you homebound. It could worsen if you develop trouble hearing or seeing or driving. Social isolation occurs when people withdraw and somehow become disconnected from family, friends and community. Any number of changes that are common to aging can trigger this issue. So perhaps it is not a surprise that nearly 1 in 5 Bangladeshi 65 and older are socially isolated, according to Science Forum. Research finds that this public health epidemic…

Not so sure if I have the right forum here, but, I came across this site after a terrible headache woke me up this morning. After taking a couple of Acamol I went back to sleep and dreamt of a horrific headache that occurred at my place of work....So, having suffered from back pain for 20 years I have to tell anyone who is interested that, yes, there is a most definite connection between real-time pain manifesting itself in dreams (or the reverse). Occasionally, I wake up with lower back pain. On more than one occasion I have dreamt of truly agonizing back pain in a dream, only to wake with similar (but not as intense) pain in my back. Is my brain trying to tell me som…
