Israel-Gaza Megathread #2
This is a refreshed megathread for any posts on the conflict between (so far, and so far as I know) Hamas and the Israeli government, as well as related geopolitics. Culture War thread rules apply.
There are vibration sensors for this, but deploying them along the entire border would be a very expensive prospect.
Ignorant question: how expensive? Vibration sensors range from like @$0.50 for "cheap vibration-triggered switch for your kid's Arduino project" to @$1000+ for "high-frequency accelerometer for your industrial turbine", but I have no idea where in that range (or beyond it?) a tunneling detector would fall ... nor how many such detectors they'd need per linear distance.
You really want a digital seismometer network. Google cache indicates that digital seismometers used to be advertised on Amazon for $8999 each. Which is a steal for defense technology, but the real engineering costs probably come from setting up the network and the analysis software to detect tunnelling without triggering on nearby trucks or nearby uses of bunker-busting munitions.
You're honest in your ignorance, but I am too. I don't have a cost per kilometer (200km?) vs depth of tunnel detection analysis. I just know that tunnel detection vs video motion analysis, vs drone/para-glider detection across the entire Gaza border needs to be calculated, put into a brief, and given to cabinet. They'll run those numbers against whatever the ethnic cleansing numbers are and eventually make a decision.
This website is a place for people who want to move past shady thinking and test their ideas in a
court of people who don't all share the same biases. Our goal is to
optimize for light, not heat; this is a group effort, and all commentators are asked to do their part.
The weekly Culture War threads host the most
controversial topics and are the most visible aspect of The Motte. However, many other topics are
appropriate here. We encourage people to post anything related to science, politics, or philosophy;
if in doubt, post!
Check out The Vault for an archive of old quality posts.
You are encouraged to crosspost these elsewhere.
Why are you called The Motte?
A motte is a stone keep on a raised earthwork common in early medieval fortifications. More pertinently,
it's an element in a rhetorical move called a "Motte-and-Bailey",
originally identified by
philosopher Nicholas Shackel. It describes the tendency in discourse for people to move from a controversial
but high value claim to a defensible but less exciting one upon any resistance to the former. He likens
this to the medieval fortification, where a desirable land (the bailey) is abandoned when in danger for
the more easily defended motte. In Shackel's words, "The Motte represents the defensible but undesired
propositions to which one retreats when hard pressed."
On The Motte, always attempt to remain inside your defensible territory, even if you are not being pressed.
New post guidelines
If you're posting something that isn't related to the culture war, we encourage you to post a thread for it.
A submission statement is highly appreciated, but isn't necessary for text posts or links to largely-text posts
such as blogs or news articles; if we're unsure of the value of your post, we might remove it until you add a
submission statement. A submission statement is required for non-text sources (videos, podcasts, images).
Culture war posts go in the culture war thread; all links must either include a submission statement or
significant commentary. Bare links without those will be removed.
Jump in the discussion.
No email address required.
