You can gain tech from another player in 3 ways.

  1. Scrap, at one of your starbases, a ship with higher tech than you possess.
  2. Have an armed ship present at a battle in which a ship with higher tech than you possess is killed.
  3. Invade the planet of a player with higher tech.

For each event (battle, scrap, or invasion), there is a 50% that nothing will be learned. If that test is passed, then there is a 50% chance for each tech category that is superior to yours that you will learn a tech. For ways (1) and (2), the only techs that count are those that went into building the ship. For way (3), all techs that the invaded player has are available. Once you learn a tech, by any method, that is it for the turn; only 1 tech from other players per turn.

Examples:

You have techs at all 10 and your opponent has techs at all 11.

You destroy a Scout A (Tech 0) with a Trans-Galactic Drive (Tech 9), a Dolphin Scanner (Techs 10, 5 and 4), and a Colloidal Phaser (Tech 10). You chance of learning a tech level is 0 (no superior tech categories).

You destroy a Scout B: the same scout, but with a Gatling Gun (Tech 11) in place of the Colloidal Phaser. Your chance of learning a tech level is :

(.5*.5)=.25
(50% for learning ANYTHING times 50% for 1 superior tech category)=25%

If you learn a level, it will be weapons (from the gatling gun)

You destroy a Scout C: Scout B with a Cheetah Scanner (Tech 11) in place of the Dolphin Scanner. The ship has superior tech in two fields, so your chance of learning a tech level is

 .5 * (1 - (.5^2)
=.5 * (1 - .25)
=.5 * .75 = .375
(50% times 50% for 2 superior tech categories)=37.5%

If you learn tech, it will be either weapons (from the gatling gun), or electronics (from the scanner).

You invade one of his planets. You chance of learning a tech level is

 .5 * (1 - .5^6)
=.5 * (1 - .015625
=.5 * .984375 = .492
 (50% times 98.4% for 6 tech categories)=49.2%

If you gain tech, it could be in any of the fields your opponent leads in.

You destroy 5 Scout Bs in 1 battle. One Battle, so chance is the same as for a single Scout B: 25%.

You destroy 5 Scout Bs in 5 separate battles. Your chances are

(1 - (1 - 25%)^5)=76.27%

For 5 Scout Cs in 5 separate battles, 90.46% (1 - (1 - 37.5%)^5).

For 5 Invasions: 96.62% (1 - (1 - 49.2%)^5).

For purposes of destroying ships, it doesn't matter if they are destroyed in battle or scrapped. It also doesn't matter if they are owned by you or another player, or scrapped by you or another player.

Remember you may only gain 1 tech level from another player per turn, via any method. In terms of turn order, scrapping takes place first, then waypoint zero invasions, then battles, then waypoint one invasions.
