I am planning to retire someday in Q1 2025, though precise date is TBD. Age 58.

Welcome to the Retirement Roll Name engineer101! You are on this Marvelous Class of 2025

Time to make amends for years of books not learn and films not watched, plus some sleeping in, dwelling cooking, biking, touring, and so on. And I’ll spend a while between now and the large day doing extra particular planning.

Sounds nice! There’s nothing like an engineer for detailed planning. We want you all the perfect in planning and having fun with a protracted great retirement filled with thrilling new adventures.

And since you have got “cooking” in your checklist of vital issues to do when you punch out of the rat race, learn this discussion board thread “Beef Roast” the place a number of Boglehead engineers tried to cook dinner roast beef – full with graph paper, coloured pencils & pens, spreadsheets, cease watches, quite a lot of meat thermometers and a number of other cookbooks with detailed instructions, all arrayed out on their kitchen counters, making an attempt to cook dinner the right beef roast as scientifically completely as attainable in keeping with exact plans

Word – these are precise quotes, nobody might probably make this up

All tools examined with engineering precision for all techniques go –

Will test the exterior show thermometer and internal-read thermometer in heat water someday to see if I nonetheless see the 3-5 diploma distinction.

Checked right this moment, they usually had been spot on (similar temp studying on every) from about 90 deg F to about 125 deg F. Then checked in my tea, and at first the instant-read displayed about 5 levels increased (say 145 vs. 140), however then I seen that that displayed temp on the instant-read thermometer modified after I moved it barely, and it was inside 1 or 2 levels after I put the ideas of the thermometers proper subsequent to one another.

So I am proud of my thermometers.

So, now your thermometers are cross-calibrated, do you have got a ample provide of graph paper?

After all I am doing a spreadsheet to plan our cooking/baking, and I exploit the common of min and max instances to plan.
Additionally, I’ve additionally learn that temp rises much less whereas resting if cooked at low temp, which is smart. My notes for recipe I feel I used final time point out with 325 temp to take away at 128-130 for goal temp of 135, and I am fairly positive that is what I did, and it labored nice. Commonest advice appears to be to take away at 125 for goal temp of 130, however particularly with decrease temp (say 200-250), I am leaning towards eradicating at 128-130.

Subsequent time, strive cooking it on the lowest temp. your oven will do. Mine is 170F. With decrease temperatures you’ll get much less overshoot. Additionally, I’m an engineer. I’ve a chunk of graph paper on the counter prime the place I plot temp. vs. time as we’re going alongside. That makes it straightforward to extrapolate the time when the roast might be accomplished.

So for the primary 40 minutes or so, temp elevated by solely about 0.2 levels/minute, then 0.5 deg/minute over subsequent hour, then 0.65 deg/minute for subsequent 40 minutes, then 0.61 deg/minute for 20 minutes, then about 0.5 deg/minute for the final 20 minutes earlier than eradicating from oven. Temp continued growing at 0.5 deg/min for first jiffy, then 0.4 deg/min for about quarter-hour, then continued to sluggish from there.

Additionally an engineer by coaching, and did similar, however entered instances and temps into my spreadsheet as I went. Used a formulation to extrapolate temp, however in fact the curve will not be linear, so predictions get higher after the primary hour or so. Right here is the plot proven earlier with calculated temps added:

We will see that on the 42 minute mark, the prediction for the 102 minute mark was means low (19 levels), because of the sluggish warmth improve charge throughout first 40 minutes. The prediction at 102 minutes for 142 minutes was 7 levels low, however after that every one predictions had been +/- 2 levels from precise. By 142 minutes I might see that the oven would attain goal temp of 125 earlier than goal time, since I had guessed 20-Half-hour per lb, and used the common of 25 minutes for planning (whereas precise turned out to be 23.25, and naturally I ought to have taken it out even sooner, so about 20-21 minutes per lb–at low finish of my guesstimated vary).

As I’ve mentioned earlier than, I will admit, engineers make me really feel insufficient – all I do is combine a Lipton’s Onion Soup packet with ketchup and pour it over a big roast, put it within the oven, lined, for 3 hours, 350 levels, and it is accomplished
