  • You can literally spend a lifetime researching the answers to your questions. Here is a very basic primer on the subject.

    OP = open pollinated. This means that this is a population of related individual plants. These are produced by growing the parents in a large field and taking all the seed. Outcrossing, off types and variation is normal. Relative uniformity is maintained by roguing out off types.

    Inbreds = are genetically mostly uniform (above 98%). These are used to produce OP’s or F1 varieties . These are created by self-pollination, sib-pollination or double-haploid techniques.

    F1 = A cross from two inbred lines. Most varieties grown from seed will produce fertile gametes with very few exceptions. Seed can be produced if you know how to. The reason F1’s exist is because of heterosis or hybrid vigor. This makes the plants of some species (if bred corectly) healthier, more uniform, and produce more than OP or inbred lines. Saving seeds from an F1 will created and F2. F2 is the generation of maximum variation and the resulting plants will all be genetically unique.

    Confusion of fertility of F1’s: Sex expression in plants gets complicated. All male or all female plants are common in nature. Plants can also have separate male and female flowers on the same plant and all sorts of varietions. You can also change the sex expression of a plant with the application of some hormones. Plant breeders often take advantage of these diffences in variety development. Only varieties that have an odd number of chromosomes (like seedless watermelons) are truly sterile.

    Saving seed - each species has its own techniques to successfully save seed. You’ll have to research how to do it for everyone. Some are very easy to do like cantaloupes. Others can take specialized skill to save like lettuce.

    Storing seed: Each species has its own storage requirements. You’ll want to look up the requirements for each one. There are wide ranges of temperature and humidity. Some species can be stored for decades. Other species are only viable for a year.

    Economics/risks of saving your own seed. Yhis gets extremely complicated fast as well. Seedborne diseases, pests, genetics etc all are parts to consider. There is no one size fits all answer.





  • Excessive Technology for students to use in the classroom is directly linked to lower test scores.

    Reasons:

    School work like any job has boring and monotonous tasks: Chromebooks etc offer endless opportunity for kids to avoid doing their work. Games, videos, or just random browsing.

    Different learning methods of different students: For many students the physical act of writing letters etc on paper or reading from a physical book helps, them retain information better than a screen.

    Slower speed - When learning something going slower improves retention and accuracy. It forces the brain to process the information more completely rather than skimming.


  • A change the view to “By Months”.

    Then look at:

    Artillery - last two months are the highest for the entire conflict.

    MLRS - Last month is the highest in 2 years.

    Anti-aircraft - last month is the highest in 2 years.

    UAV - the last 6 months holy fuck… Ukraine is knocking a shit ton out of the sky.

    Cars/trucks - the last 6 months Ukraine is absolutely wrecking these. Since soldier casualties are not spiking the additional destruction is logically not from assault buggies etc but logistics. So last spring averaged 3500 vehicles destroyed, so the likely 5,000 of the 8,600 vehicles destroyed in May were logistics. That’s a lot of burning vehicles.




  • I personally like where Olev Vinn went with it.

    Recently, paleobiologist Olev Vinn has suggested that the great filter may exist between steps 8 and 9 due to inherited behavior patterns (IBP) that initially occur in all intelligent biological organisms. These IBPs are incompatible with conditions prevailing in technological civilizations and could inevitably lead to the self-destruction of civilization in multiple ways.


  • I personally like to believe that life is not rare because life fucking finds a way and all that.

    Intelligent life is likely not rare. On our planet there are several species that might be considered intelligent like elephants, whales, dolphins, covids etc.

    Intelligent, extreme tool building life at a detectable technology level from space is extremely rare. I mean seriously, humans have only been detectable from space for less than 125 years out of the 400-500 million years with large multicellular life on this planet.

    We developed the ability for a global extinction event from nuclear warfare 80 years ago and we are currently on pace for a global climate catastrophe in the next 200. At the current rate we’ll be lucky to be detectable from space for 200 years.


  • 2 different airframes.

    The full payload like the FP-1 made out of more durable materials and designed travel long distances and blow shit up

    The “decoy” is made as cheaply as possible with a radar signature designed to look the same as the full-payload. They can travel long distances as well.

    By daylight they look different, at night on radar they look very similar. A good radar technician might be able to spot the difference and not waste the ammo on a decoy.

    So Ukraine puts explosives on the decoys and turns them into AA hunters. This forces the AA to fire on all contacts, expending their ammo rapidly. It also gives Ukraine a swarm of armed “decoys” to target any AA. Oh what’s better, announcing that they are doing it makes it MORE effective. The only thing that AA crews can do to avoid becoming a target is to NOT fire.
