The second man observes this and when the first man reels in an empty hook; he theorizes that the first anglers hook is too small. He promptly reels in and ties on a larger hook to his own pole and cast out again. Several minutes later his line tightens and his reel begins to squeal. He grabs it firmly and pulls hard in the air, and like the first angler his line falls limp. Only when he reels it in, he finds that his bait is still there, only void of a few scales.
The definition of scientific method is simple, first we form a theory and then we try to reduce it down to something that is testable and provable; this is known as the hypothesis. We then weigh the variables. In fishing the variables can include a number of things such as weather, bait, water temperature, gear, etc.
Many anglers are scientific researchers and they are not even aware of it. They build on tips from their dad or granddad, and then put them to the test in a natural setting. This is a form of research. The only difference is many fishermen draw their conclusions and then keep them safely to themselves. They do not rush to publish them in an article or journal for all the other fishing researchers to evaluate. However, this does not mean they did not use the scientific method for drawing their conclusions.
The wise angler draws upon his past experiences and determines that the water temperature, the time of day, and the bait as well as the hook are correct to catch these fish. So he questions; why is no one able to catch these elusive trout?
Whether you believe it or not, fishing is a science. Like most scientific researchers fishermen develop their theories from questions that arise through personal experience, tales told from other anglers, and sometimes out right myths. The only way to validate these theories is to zero in on the variables and test them against the fish themselves.
Why hello, Venus.
NASA’s Parker Solar Probe, a well-armored spacecraft that’s observing the sun closer than any mission before, swung by Venus in July 2020 and snapped some opportunistic images. On Wednesday, the space agency released a particularly vivid image from this near pass.
“#ParkerSolarProbe captured this stunning view of Venus during its close flyby of the planet in July 2020,” NASA tweeted.
There are some cool things to see in this shot, which was taken by the probe’s only imager, the Wide-Field Imager for Solar Probe. (It’s designed to take images of the sun’s atmosphere and ejections from the sun, but can capture objects like Venus, too.)
The dark area on Venus is a massive highlands region called Aphrodite Terra, which extends two-thirds of the way around the planet. It’s seen as darker because it’s higher in elevation and cooler than the surrounding terrain.
The light rim around the planet could be a phenomenon called “nightglow,” as some interacting atmospheric particles emit light during the night.
The streaks could be caused by a few different things, like sunlight reflecting off of space dust, or even specks from the spacecraft after impacts with space dust.
Plenty of stars in the deep cosmos are visible behind Venus.
To pass through the sun’s outer atmosphere, the Parker Solar Probe swings close by Venus, using the planet’s gravity to “bend” its orbit closer to the sun. This particular flyby brought the probe some 7,693 miles from Venus, a planet shrouded in thick clouds.
