Wave propagation basics — stress waves in solids, why ground vibration and airblast are different phenomena.
Airblast is not ground vibration. Windows care about dBL.
A university, a code, or a named issuer owns the long course. What we host is how this shows up on a demolition job — not a degree, not a licence.
On a plot: if you cannot say what is known vs assumed, do not send a number or a method. Overturning and energy show up as a method call, not a formula sheet.
Site hours with someone who already has judgement have no video substitute. Tick only when you have an artefact.
Before you tick
- I can name what is known vs assumed.
- I have an artefact, not only watch-time.
