One of the best things about travelling is seeing how things can be done differently and that 'alternatives are possible'!
Absolutely mind blown to discover that all public transport is free across Luxembourg. Free buses. Free trams. Free trains. For residents and visitors. No tickets. No tapping in or out. No pesky apps. Just walk on and walk off.

Since there is some discussion that NIH institutes should not simply use paylines to determine which grants to fund, I thought I would share some old data.
These are plots of funding probability fas a function of percentile score for 9 institutes.
