How to unlock the Scientific Pursuits achievement in Fallout 3 - Definitive Guide
1) *OPTIONAL* Talk to Three Dog at Galaxy News Radio about your dad, and complete the corresponding quest.
(Thrydwolf has confirmed that the achievement will pop even if you skip the Galaxy News Radio quest. Randy2084 has claimed that skipping GNR and Three Dog may cause a different achievement, "Following in His Footsteps," to glitch, though that is the first time I've heard of it. If anyone else can confirm this please do so in the comments.)
2) Travel to Rivet City, and talk to Dr. Li about where your dad went. DO NOT HEAD TO THE JEFFERSON MEMORIAL BEFOREHAND, AS THIS WILL CAUSE THE ACHIEVEMENT TO GLITCH.
3) *OPTIONAL* Head to the Jefferson Memorial, go into the Gift Shop, and from there go into the Rotunda. Listen to Holotape #10 to discover your dad's location.
(sjpsjpsjp has confirmed that the achievement will pop even if you skip this step and go directly to step #4.)
4) Head to Smith Casey's Garage, flip the electrical switch on the wall inside, head down the stairs, and enter Vault 112.
5) Talk to the Robobrain inside and get the Vault 112 jumpsuit and put it on. Head downstairs to the pods, enter the unoccupied one, and you'll end up in Tranquility Lane.
If you have followed this guide, you should get the achievement upon arrival.
After speaking with Three Dog, head to Rivet City to try and find your father. Head to the Science Lab and speak with Dr. Li to learn that he has yet again moved on. Set off for the Jefferson Memorial and enter the door labeled "Gift Shop." Head to the control room of Project Purity and find Audio Tape 10. Listen to it to find that he has gone to Vault 112. Set off for Vault 112 where a robot will ask you to put on a new outfit and use one of the Tranquility Loungers.
See Scientific Pursuits for more specific info.
Story Related but Highly MISSABLE
WARNING: Contrary to popular belief this trophy is not glitched but it is highly missable. You can miss out on this trophy for the current playthrough by discovering/exploring the Jefferson Memorial, Rivet City, Smith's Garage or the area immediately around them before talking to Three Dog and being explicitly told to go there by this specific mission.
After handing in the Galaxy News Radio Quest, Three Dog will tell you to find a Dr. Li in Rivet City. Getting to Rivet City will not be easy as you have to traverse several underground Metros but there is another way if you get stuck, Harry Fast Travelled back to the Farragut West Metro Station. There's only a couple of Centaurs and you can get to Rivet City pretty easily then.
Once you get to Rivet City, you'll have to speak to someone on the intercom to get the bridge moved. After gaining entry, find the Science Labs where Dr. Li will be working and after Speaking with her you'll be told to go to Project Purity in the Jefferson Memorial but pick up the Bobblehead that’s on her desk before you leave.
When you get to the Jefferson Memorial, watch out for Super Mutants as they'll be lots of them both outside and in. Your goal when you get inside is to find the Research Holotapes your Father left behind and one in particular, they're in Rotunda in the lab on top of the machine just outside the inner doors. Once you have the tapes, listen to them and afterwards you'll be given a map marker for Smith Casey’s Garage (which is on the West side of the map near Evergreen Mills).
After killing the mole rats and Radroaches inside the Garage, press the switch on the wall to reveal a secret tunnel that leads to Vault 112. Once inside the Vault you will be met by a Protectron who wants you to wear the appropriate clothes and will give you a Vault 112 Jump Suit, put this on. You then need to find and enter the only remaining unoccupied Lounger in the central area.
Once you enter the Lounger, the Quest will end and the trophy will pop.
