Kerman's Law

[kookoo_gr]

When entering a planet's SOI your ship will always be anti-normal and will have to correct the orbit to the desired one.

Deadly Rentry derivation: the parachute burns down first

90% of space center crew is bussy retrieving crafts all arround the globe, before you can actualy build crafts and/or wheels

As soon as you do something in KSP cool or interesting enough to share on the forums you will read a thread where someone does the same thing better/faster/more efficiently.

And now I shall introduce the Centipede's Dilemma into the mix with: any maneuver you've done a thousand times before and have down pat can and will fail the moment you stop to think about it.

[AlexinTokyo]

AiT's corollary to Kerman's law:

The chance of developing a sudden, unexpected twitch in your mouse hand or wrist is proportional to the square of the amount of time spent fine-tuning a given maneuver node and simultaneously inversely proportional to the tolerance for error of said node.

You will always be a few points shy of enough science to buy your next technology upgrade.

[Pecan]

Here's a few:

Atwood's law: Any vehicle that can be powered by ion engines will eventually be powered by ion engines

Parkinson's law: Payloads expand to fill the launch vehicles available

Pecan's rule: Use of the term 'SSTO'is inversely proportional to the meaning of 'SSTO'

Peter principle: Transfer vehicles vehicles are stretched to their level of incapability

[Superfluous J]

The probability of Kraken failure is directly proportional to the time since your last quicksave.

Corollary: Autosaves will always take place at a time K+1 second, where K=the time of any given Kraken event.

[wasmic]

The probability of remembering to quicksave goes down as one approaches a dangerous maneuver or a Kraken attack.

As the time invested in the design of an SSTO tends toward infinity, the probability that the SSTO will work tends towards infinitesimal. Paraphrased: The probability of an SSTO working is inversely proportional to the amount of work put into it.

A kerman law:

thou shall strut like a peacock which shall fly with thunder.

[xcorps]

Thou shalt return to VAB 3 times before going to space. No more. No less. After thine 3rd return, three being the third return..not 2 and less than 4...thou shalt forgo thy action groups, as thou has already returned to VAB thrice.

[StrandedonEarth]

This could probably be a thread in it's own right, but what the heck...

If at first you don't succeed:

-Try reading the instructions

-get a bigger hammer (forklift makes a great hammer)

-Get a bigger booster

-get more boosters

-Put Jeb at the controls

The more perfectly you set up an aerobraking encounter with a planet, the more likely it will get messed up by passing through its satellite's SOI.

Looking at you, Ike.

The greater the number of Kerbals on EVA the higher the probability that the next Kerbal exiting the hatch will be ejected from the craft at a velocity greater than 1 km/s relative to other nearby bodies, usually straight at another Kerbal (s).

This happened last night to me in orbit around Ike...sigh.

[tmanrules97]

I propose that we rename the multiple laws (since there is only one Murphy's law) to the Laws of Kermodynamics.

I also propose the Zeroth law of Kermodynamics: If two ships are docked together and a third one is docked, then you will not be able to undock any of them.

[Roastduck]

"If your new design launches and flies cleanly you have most likely forgotten something critical."

Hey, no solar panels. Or antenna. Or landing gear.

Oh my god, this so hard.

[Alchemist]

Laws of Kerbodynamics? Let's see:

First law: Spacecraft = Usefulness + Aesthetics. Conclusion: well working craft will look terribly, a pleasant design will be unflyable.

Second law: With every iteration of problem solving the mass of your craft will only grow.

Third law: No extra mass is possible only for a perfect craft with zero error margin

[-root]

A craft will only fail at the worst time possible.

Eclipses only happen when you need to make a maneuver.

Landing spots are never flat

Anytime you need to make a correction burn on the fly, you will burn the wrong way first

The ground is always closer or further away than you think it is.

1st Kerman law:

No Kerbal can live forever in one save.

[Abel Military Services]

2nd Kerman's law: 

Nobody can play KSP without explodes.
