A puzzle from More Problematic Recreations, published by Litton Industries in the early 1960s:

A truck, when fully loaded, can carry enough fuel to take it half-way across a barren desert. If the truck can return to its starting point as often as is necessary, what is the minimum amount of fuel required to take it all the way across?

Mississippi in Minecraft

AtmosphericBeats makes real-world Minecraft maps based on geographical data and their latest creation is a 1:20 scale map of Mississippi.

This work is a representation of the State of Mississippi, USA, on a 1:20 scale with biomes, vegetation and other natural features derived from OpenStreetMap and high resolution land cover datasets

These are much better than the simple heightmap-conversion types of "real world" Minecraft map that were always a thing. — Read the rest

The full guide to London’s museum memberships as Christmas presents

by ianVisits

If you want to give something this Christmas that your recipient can use all year round, rather than socks and fragrances… give them membership to a museum or gallery they love.

Most museums have some form of membership scheme and usually offer a range of goodies, such as free entry for museums that charge an entrance fee, newsletters, and the bigger venues tend to have private members’ events in the evenings or priority booking for public exhibitions.

As a present, it’s lovely to offer, as people who love a museum now find they are getting invites to private events and tours and can go into paid exhibitions for free as often as they like.

It’s a whole year of joy.

I’ve trawled around looking at the venues I am aware of and seeing which have a membership scheme with benefits for the member and listed them below. The costs listed below are generally for payments by credit card for buying as a present, although most offer discounted rates if you want to pay by recurring direct debit.

If buying for a partner, most offer duel-memberships at a favourable rate, so you can share the fun together.

A museum membership isn’t just for Christmas; it’s for.. well, a whole year at least.

Buy These Garden Essentials on Sale Before Fall

by Amanda Blum

Sometime last week, the season turned. The heat broke with a dramatic rainstorm, and although it returned to 80 degree days after, it was clear summer was at its end. The air just smelled different, and I could see the local squirrels’ behavior changing into prep mode.

Actually, Stamps Are a Great Stocking Stuffer (I’m Right About This)

by Claire Lower

As I’ve mentioned previously, my family takes stockings very seriously. A good stocking is all about balance. Some candy here, a clementine there, some cute beauty products to round it all out—you want to create a varied collection of tokens and trinkets to keep the stocking from being one-note.

Science and art at the National Gallery’s Copernicus exhibition

by ianVisits

A painting of the Polish astronomer, Nicolaus Copernicus is currently on display in the UK for the first time ever.

The painting, Astronomer Copernicus, on display in the National Gallery is also by one of Poland’s most famous painters, Jan Matejko’s (1838–1893), and while much-lauded at home, he is rather less well known outside his home country.

The painting, a huge canvas, was painted in 1873 to mark created to celebrate that year’s 400th anniversary of Copernicus’ birth, although the painting was not included in the program of the official celebration. Matejko had to arrange to have the painting put on display during the anniversary on his own, and donated ticket fees to charity.

It was later bought by Kraków’s Jagiellonian University following a public fundraising.

The dramatic composition shows Copernicus kneeling while reaching up to the night sky. He was reputed to be as good looking as he is shown here, with long flowing hair, although the model who stood in for the painter was a friend of the artist, the local doctor, Henryk Levittoux, who was evidently equally gifted in the luxurious locks department.

If you look carefully you might see that he is wearing a black skullcap as a sign of the clergy, for while Copernicus challenged orthodox ideas, he never broke from the church, and argued that there was no contradiction between science and religion.

Copernicus is shown surrounded by the tools of the trade of early astronomy, although they are not literal representations, as two of the objects in the painting were invented after Copernicus died. Nickpickers also complain that Copernicus seems overly brightly lit for a man at night seemingly with just one small lantern to observe the stars.

However, it’s a romantic vision of a lifetime’s work, not a literal representation of a specific moment in time.

The dark room that houses the painting has been decorated with stars, and not just randomly — they represent the sky as it would have been seen in the early hours of the morning Copernicus died on 24th May 1543. Apart from the painting itself, there’s an early sketch which shows some differences from the final work, and also a copy of De revolutionibus orbium coelestium showing his most famous observation, that the earth is not at the centre of the solar system.

The painting is on loan from the Jagiellonian University, where Copernicus also studied, and the painting hangs in the Senate Chamber, where it rarely leaves, and even rarer leaves to go outside Poland.

This is a rare chance to see not just a great painting, but also one that reflects one of the major moments in European science.

The exhibition, Conversations with God – Jan Matejko’s Copernicus is open at the National Gallery until 22nd August 2021.

Entry is free, but tickets need to be booked in advance. There are three one-way routes around the gallery at the moment, but this exhibition is next to the gallery exit, so you can’t miss it regardless of the route you take. On busy days there can be a small queue outside the exhibition room as there is a limit on the number of people allowed in at the same time.

As a nice touch, the signs in the exhibition are in both English and Polish.

The event is free, although a collection tray will be passed around during the (short) toilet-break in the concert with a suggested donation of £10.

Make Sourdough-Like Bread Without a Starter

Make Sourdough-Like Bread Without a Starter

There are few things as good as a fresh, hot loaf of real sourdough bread but, due to its finicky nature, it can be a hard thing to nail at home. Luckily, Epicurious has a cheat for us, and it involves fresh yeast.

http://lifehacker.com/309730/bake-yo…

The method, which comes from baker Adam Leonti of Brooklyn Bread Lab, and it is one of the easiest, most elegant ways to get tangy, chewy bread that is pretty close to the real thing, without having to deal with wild yeasts or strict temperature management. All you have to do is swap out instant or dry active yeast for fresh cake yeast. This type of yeast—which comes in a solid, compressed block and has a fresh, sour smell—can be purchased in the refrigerated section of most grocery stores. Once you’ve acquired it, throw it into a no-knead bread recipe and bake it like you would any other simple, rustic loaf. The result won’t be true sourdough, but it will be fairly close, and whole lot easier.
