@ProfBrianCox hey Brian. Love you work. You were at Siding Spring observatory when I had a school group out there. I’ve been teaching physics for 25 years and often use your gravity video with ball and feather. Wondering if you have footage of the full speed air-free drop? Thanks

@AlanKohler please explain why petrol is still 90cpl and 115 cpl in regional areas. Will prices drop significantly in coming months.

@mikasounds loving your choices of NY tunes. Re: bike dreams. Wholehearted endorse it. Got licence at 42, and love getting away into Aust bush with backpack and tent.

Nice!

[Dave Moffitt @s0diumman]

@DoctorKarl Thanks Karl. Your solution assumes the centres of both shapes are known points.
Can you solve it without knowing the location of these points?

[Dave Moffitt @s0diumman]

@DoctorKarl solution to circle square maths problem is bothering me. It relies on finding the centre of each, but doesn’t explain how to do this empirically in a field. I think that’s what your first caller was trying to explain.

@sacky85 @DoctorKarl Not completely correct. Not sea floor spreading. Volcano cone becomes surrounded in coral reef (fringing reef) then the volcano collapses and sinks meanwhile the coral continues to grow the ring. Ultimately ends in an atoll

What do you think are essential ICT skills for students to master at school? Edit my GoogleSheet at https://t.co/H95M8kqfTM to share yours.

@sunman_geoff @Solar_Quotes So Geoff, what should I do to de-couple from these grid-charges if in town? Is off-grid feasible in town?

Re-Think ICT in Classrooms. Reading #newscientist Oct 17 opinion "Bottom of the Class". Is it time to move back to giving PCs when needed?

[Dave Moffitt @s0diumman]

@weezmgk @DoctorKarl totally agree that the water vaporises and carries up an oily mist that flash ignites with available O2.

@DoctorKarl Hi karl, you had a caller some time ago on JJJ ask about water on an oil fire. I read this in an old book
