We had four frantic live chats in Detection today, there was especially a lot of laser chat going on. The engineers have also been asked over 200 questions from you so far, so keep them coming, and remember to VOTE!

Today’s highlights:

• Amanda answers an interesting question:

Do you ever think about the people’s lives your inventions have saved?

• Ben describes his work:

ellathompson : @ben Sum up your work in 5 words…
bendrumm : @ellathompson – interesting, fun, challenging, mind boggling (some of the physics to do with our particle accelerator I will never understand!)

• Gary manages to shatter our laser illusions:

critchers : Gary LAD do you use lasers for secret missions?
niamhtitterton123 : Can lasers be weaponised?
garyboorman : @all A quick note about lasers – lasers in movies aren’t quite the same as real-life!

• And Samer gets that laser excitement, back on track:

What exactly do you mean by “blowing things up with lasers”?
