Interestingly trans fats are straight and cis fats are bent. It's just physical chemistry, I don't make the rules

en.wikipedia.org/wiki/Trans_fat
A screenshot of the Wikipedia article on trans fats, showing three kinds of fatty acid; because the double bond between carbon atoms in the trans fat has the hydrogen atom—which introduces a bend for each carbon—on opposite sides (hence "trans"), the double bond is rotationally symmetrical and the two hydrogen bends oppose each other, resulting in a straight configuration. The cis fat has the hydrogen atoms on the same side (hence "cis") and so is bilaterally symmetrical, but not rotationally symmetrical; this means the two hydrogen bends add together and result in a bent configuration. The third kind of fat shown is fully saturated, with no double bond, and hence also straight. Saturation, in this context, means that the fatty acid has as many hydrogen atoms as the carbons can hold. A polyunsaturated fat will, by contrast, have multiple double bonds because there are many carbon atoms with fewer hydrogen atoms than they can hold. I have no idea what happens if you get a fatty acid with a triple bond in it, but it would probably be straight although it might also be unstable.

Just getting my pythagorean ducks in a row/column
A spreadsheet, showing ratios of powers of three over powers of two. I've used conditional formatting to identify only values that are between 0.5 and 2.0, which should give me two scales of pythagorean tones within a couple of octaves. This means, in theory, I can choose a truly horrible tuning and put a melody in it (and I will).

This plant is growing in my garden, near the tub I grow thyme in. The leaves, when crushed, smell like lemon more than they do thyme. Can anyone positively identify it? Is it definitely edible or possibly poisonous?
Something growing in my garden, with white four-petalled flowers about 5mm across and oval leaves about 3mm long and half as wide, growing close to the ground in a kind of mossy coat with long, thin visible stems beneath.

If it helps, here are some other songs about barracudas
As one goes by (Tune-As Time Goes By) It's called the Barracuda And nothing could be cruder Still flying in the sky. You really can't believe it's true As one goes by. Observer and Air-Gunner Weigh down this seven-tonner, And they will tell you why They're happy to be on the ground As one goes by. High-strutted tailplane Very out of date, Radar and wireless Adding to the weight, High wing and dive brakes Such a fucking crate Could never really fly. That two ton pair of legs Is just the bloody dregs, That Fairey's can't deny. The RAF just rub their eyes As one goes by. Fairey! Fairey! (Tune - Daisy, Daisy) Fairey! Fairey! Give me your answer do, What is wrong with my Barracuda Two? Dive-bombing has strained my structure, I've got a stressed-skin rupture, And rivets pop, along the top And one of them might hit you. Fairey! Fairey! What are we going to do? Nine Wing's grounded, looks pretty bad for you. When my Barra falls asunder I'll be a wingless wonder. I'll jump out quick, and bring my stick And stuff it right up you! Barracuda II (Tune - Any Old Iron?) Any old iron? Any old iron? Any, any, any old iron? Talk about a treat Torpedoing a fleet, Any old cruiser or battleship you meet. Weight six tons, no front guns, Fuck-all to rely on. You know what you can do With your Barracuda Two Old iron, old iron! Any old iron? Any old iron? Any, any, any old iron? The engine is a teased Rolls Royce, A Merlin 32 and it ain't our choice Open up the throttle And the whole fucking lot'll Wail like an air raid siren. You know what you can do With your Barracuda Two Old iron, old iron!

Are you: – vexed by vespids – harried by hornets – irritated by ichneumon wasps? NO LONGER! The WASP ELECTRO VORTEXION is here! WASP ATTACK! FACT: the European wasp is the most aggressive stinging insect in the world. FACT: the Asian Giant Hornet is spreading from Japan through Europe and is coming for England maybe sooner than you think. FACT: wasps attack the nest of bees and our agriculture depends on bees. Wasps are a menace. Like them or loathe them, you just can't help but loathe them. They steal our food, kill innocent bees and buzz irritatingly in through your open bedroom window just as you're getting to sleep. Consider the following familiar scene. It's August, and perfect picnic weather. You've taken the family out to enjoy the last of the summer; you're just settling down to your jam sandwiches, when suddenly, the wasps descend in a malevolent black-and-yellow cloud of sting-tipped vespid mayhem. At once your guests are up off the picnic rug, dancing like imbeciles and squeaking ineffectually while this insect menace tucks into the provender you have so thoughtfully brought. You are a million times the size of a wasp, but it has you dancing to its nasty little tune. Well, no longer thanks to the WASP ELECTRO VORTEXION! Simply point one at a wasp, pull the trigger, and watch the powerful suction draw the little winged bully into the machine's interior, where it will be electrocuted by a 4000V grid with a satisfying, meaty snap. The WASP ELECTRO VORTEXION comes in three sizes: the pocket-sized Picnic, the powerful but portable Camperman and for those of you who like to take the fight to the wasps, there's the ultimate in exterminators: the WarHunter. HOW IT WORKS: anatomy of the Wasp Electro Vortexion The WASP ELECTRO-VORTEXION might sound like a miracle of modern boffinity, but in fact its operation couldn't be simpler! A powerful compressor pumps air along a duct to the mouth of the device where it passes over a shaped surface, rather like the wing of an aeroplane. The high-speed air inside the device's nozzle creates a powerful suction that draws in the offending … DEFEND YOURSELF with the WASP ELECTRO-VORTEXION The Picnic Simple and basic, the Picnic runs on a rechargeable battery that is sufficient to kill 250 wasps far more than will be required by an average user. It can be carried in a handbag or in a stylish holster (sold separately). The Camperman Gone on holiday and discovered that you've driven your motor-home into a field with a wasp's nest in it? The Camperman is for you! It runs off the lighter socket of your car or off a small yet powerful battery pack (sold separately). The Camperman is also powerful enough to deal with hornets up to 5cm in size sufficient to take on the formidable Yak Killer or Asian Giant Hornet* with ease and a beekeeper wishing to protect his hives from these marauding beasts can even adjust the grille pitch to kill hornets dead but leave honey-bees unharmed. The WarHunter Whether you work in pest control or you've simply decided to take the battle to the wasps the vehicle-mounted, telescopic WarHunter is the biggest, baddest Wasp Electro Vortexion money can buy. The price includes a universal mounting bracket and for a small extra charge our trained engineers will wire the power inverter directly into the alternator of your car, lorry or tractor. The telescopic nozzle can be extended up to ten feet to reach awkward trees, the grille pitch can be changed from the control panel in the vehicle's interior, and the electrical grille can be neutralized altogether for a beekeeper who simply wishes to collect his swarm from a tree! *No responsibility is accepted for injury or death resulting from attacking Asian Giant Hornets. SCHMIDT STING PAIN INDEX A GUIDE TO INSECT VENOMS 1.0 SWEAT BEE Light, ephemeral, almost fruity. A tiny spark has singed a single hair on your arm. 1.2 FIRE ANT Sharp, sudden, mildly alarming. Like walking across a shag carpet and reaching for the light switch. 1.8 BULLHORN ACACIA ANT A rare, piercing, elevated sort of pain. Someone has fired a staple into your cheek. 2.0 BALD-FACED HORNET Rich, hearty, slightly crunchy. Similar to getting your hand mashed in a revolving door. YELLOWJACKET Hot and smoky, almost irreverent. Imagine WC Fields extinguishing a cigar on your tongue. 2.5 HONEY BEE AFRICANIZED HONEY BEE EUROPEAN HORNET 3.0 RED HARVESTER ANT Bold and unrelenting. Somebody is using a drill to excavate your ingrown toenail. PAPER WASP Caustic & burning. Distinctly bitter aftertaste. Like spilling a beaker of Hydrochloric acid on a paper cut. 4.0 PEPSIS WASP Blinding, fierce, shockingly electric. A running hair drier has been dropped into your bubble bath. BULLET ANT Pure, intense, brilliant pain. Like walking over flaming charcoal with a 3-inch nail in your heel. ASIAN GIANT HORNET Often fatal. Like a hot nail being driven into your leg. The Schmidt Sting Pain Index is based on the work of Professor Justin O Schmidt and is reproduced with thanks.
