Hanno: That's very cool. Does it take into account the decreasing mass of the lunar lander as the fuel is consumed? Does it take into account that when the gas is all gone and your are not on (or very near) the ground it's game over?

Heater-
Here's the code to land both a "fuzzy-logic" controlled lander, and a human-controlled lander. Currently, it does not take mass/fuel into account. Should take 2 lines of code- want to add them?
repeat 'keep landing forever...
height:=start_height 'initialize lander's height and speed
speed:=start_speed
height2:=start_height 'initialize lander's height and speed
speed2:=start_speed
repeat while height>0
'Fuzzy Control
f.fuzzifyA(height,FMHeight) 'fuzzifies Height into fuzzy register A
f.fuzzifyB(speed ,FMSpeed) 'fuzzifies Speed into fuzzy register B
f.doandRule(FRThrottle) 'calculate new Throttle with ThrottleRule
throttle:=f.defuzzify(FMThrottle)'defuzzify Throttle to a number
f.share(@fuzz) 'share fuzzy result with Viewport
'Physics
speed+=(acc_gravity-throttle)/dt 'moon's gravity increases lander's speed
'throttle decreases speed
height-=speed/dt 'each dt, height decreased by speed/dt
'same for lander #2
speed2+=(acc_gravity-throttle2)/dt
height2-=speed2/dt
waitcnt(cnt+clkfreq/dt) 'wait by dt

According to Eureka they landed on '62 but didn't go public till the '69. But how to believe them when everything science-related sucks in that series ?. Well, I love the "ultra-high-tech" oscilloscopes, from the 60s and 70s that pop-up from time to time (Have a look at the last episode). Haven't seen any real top-of-the-class Oszi so far... The Tek 425 must be from the Original Galactica...

Do they still teach Newtonian Physics in high school ?
Not since fuzzy logic was invented
