Unscramble the Blue Letters

What about scientific discovery? What about driving innovation? Well, this looks like a picture of vutralliy nothing. What it is, is a picture of the scptreum of hydrogen. See, back in the 1880s, 1890s, many scientists, many observers, looked at the light given off from atoms. And they saw strange pictures like this. What you're seeing when you put it through a prism is that you heat hydrogen up and it doesn't just glow like a white light, it just emits lihgt at particular colors, a red one, a light blue one, some dark blue ones. Now that led to an usddtineannrg of atomic structure because the way that's explained is amtos are a single nucleus with electrons going around them. And the econelrts can only be in particular places. And when they jump up to the next pacle they can be, and fall back down again, they emit light at particular colors.

Original Text

What about scientific discovery? What about driving innovation? Well, this looks like a picture of virtually nothing. What it is, is a picture of the spectrum of hydrogen. See, back in the 1880s, 1890s, many scientists, many observers, looked at the light given off from atoms. And they saw strange pictures like this. What you're seeing when you put it through a prism is that you heat hydrogen up and it doesn't just glow like a white light, it just emits light at particular colors, a red one, a light blue one, some dark blue ones. Now that led to an understanding of atomic structure because the way that's explained is atoms are a single nucleus with electrons going around them. And the electrons can only be in particular places. And when they jump up to the next place they can be, and fall back down again, they emit light at particular colors.
