Since 2015 is the 70th anniversary of the end of World War 2 (WW2), C-SPAN has been running a number of oral history interviews with people who worked on the Manhattan Project. I have found these interviews very interesting. You can find them on YouTube and watch them for yourself.
After watching one interview with a worker from the Y12 enrichment plant, I decide to look for some additional background material on the work done on the Manhattan Project. It was during this research that I watched a video in which engineer made the statement that only 900 grams of

I should note that you will find a number of values listed for TNT's energy release – the value varies by how you define the release characteristics. For example, while the heat of combustion is listed as 14.5E6 Joules per kilogram, the energy released in the act of exploding is listed as 4.184E6 Joules per kilogram.
Conclusion
It is hard to believe the amount of energy that is released by splitting atoms. An even more unimaginable number is the amount of energy released by the complete annihilation of matter, such as with matter/antimatter interactions.
