## Main Question or Discussion Point

Hello. I am trying to get the hang of tensors. I saw this written in http://mathworld.wolfram.com/MetricTensor.html

I just wanted to make sure it was correct.

[itex]g^{\alpha\beta}[/itex] =[itex]\widehat{e}^{i}\ast \widehat{e}^{j}[/itex]

Which says that the dot product of two unit vectors equals the metric tensor. Like I said, I am very new to this stuff and I'm just trying to get the hang of it.
