Some video of the deluge. Viewer beware. ( I find she babbles a bit much, but that's just me, 229 subscribers she has ) 1. Question of where all the water came from. 2. Blocked lake upriver posing a risk of secondary water cascade 3. Seismic recordings were that of the deluge ( not an...

Some discussion from Jakob Steiner, a geoscientist at the University of Graz in Austria and Glaciologist Simon Cook, University of Dundee, Scotland. Satellite image at the 1:42 mark.

Right. I incorrectly used the Cp for change in degree for water, instead of that for ice. Equations 1. Potential Energy of 1 kg of water at height E = m g h --> mass 1 kg, g = 9.81 m/s/s, h = 1200 m ( Assuming 1200m as height, and not glacial path length ) E = 11.8 kJ Temperature rise of 1 kg...

You might want to factual check for sensationalism in this one paragraph: Equations 1. Potential Energy of 1 kg of water at height E = m g h --> mass 1 kg, g = 9.81 m/s/s, h = 1200 m ( Assuming 1200m as height, and not glacial path length ) E = 11.8 kJ Temperature rise of 1 kg water from...

It is kind of difficult to high five on what the white stiff really is unless one can go and poke it with a stick. One reservation I do have is that the concrete looks to have surface that has been sealed. Any direct reaction of acetic acid and concrete would then have been hampered, and to...

nanobot replicators?? Is that what this is?

What is the self-accelerating decay time line? Hours, days, years before the film is unusable? What you see is typical for concrete. The white stuff is efflorescence, the deposition of salts onto the surface, either by evaporation of water that has moved through the concrete and carried salts...

A re-hash with some links of the complexity of present day timekeeping. The world depends upon accurate time stamps, past present and future, so all operating systems and programs should determine such things as local time where you are located, local time where some one else is located, in...

Eisner reference to the Homicide graph https://www.vrc.crim.cam.ac.uk/sites/default/files/manuel-eisner-historical-trends-in-violence.pdf The term 'Homicide' has a connotation of direct personnel emotionally driven conflict resulting in a death, and may not actually represent the violence...

They put swimming pools on the top of high rise buildings, for the view. So far safe. In an earthquake, the water will slosh back and forth if the building sway frequency matches the resonant slosh frequency of the pool water. Instances where the seige in the pool is so severe, the wave...

More dangerous as a spectator than contestant. I have seen videos....

Just wondering... Are people ready for an autonomous robot pothole machine on their street? They might be wary of a road machine wandering around in its own and demand a human supervisor as a safety precaution, so that some curious kid doesn't get too close and end up as pavement. Any liability...

In a sprawling, 165-page essay that became required reading in Silicon Valley, the former OpenAI researcher positioned himself as a kind of prophet for the coming age of artificial super intelligence. The crash marks a dramatic turn for Aschenbrenner, who launched the fund after gaining...

Already been done. https://en.wikipedia.org/wiki/AeroVironment_Nano_Hummingbird. Flapping wing drones are easier to make than what one would think from narrator in the video seems to imply. They have been around for quite some time. Glidder --> flap the wings a bit --> propelled flight. Drone...

That is scary! The human mind will not be able to keep up with the extremely rational and logical thinking of silicon. Capt Kirk was wrong. It is not the robots that will self destruct due to 'does not compute, ... ".
