 | Capture lets you extract parts of code which can be used in other points of the template or even layout file. |
| content_for("name") is a wrapper for capture which will make the fragment available by name to a yielding layout or template. |
| Capture allows you to extract a part of the template into an instance variable. |

Electron capture - Wikipedia, the free encyclopedia (400 words) |
| Electron capture is a decay mode for isotopes that will occur when there are too many protons in the nucleus of an atom, and there isn't enough energy to emit a positron; however, it continues to be a viable decay mode for radioactive isotopes that can decay by positron emission. |
| In this case, one of the orbital electrons, usually from the K or L electron shell (K-electron capture, also K-capture, or L-electron capture, L-capture), is captured by a proton in the nucleus, forming a neutron and a neutrino. |
| Since the proton is changed to a neutron, the number of neutrons increases by 1, the number of protons decreases by 1, and the atomic mass number remains unchanged. |
