One way (of many) to prove that the Earth is a sphere is to compare the length of a shadow cast by the same object at the same time of day at different locations. Because we live on such a rotund rock, the incoming rays of light from the sun reach us at different angles of incidence depending on our position. Measuring shadows this way implements the same approach that Greek astronomer Eratosthenes used to calculate the exact circumference of the Earth 2,267 years ago!
Shark week starts today and to celebrate we’ll be launching a new legging print this coming week, inspired by one of the largest marine predators - the tiger shark, Galeocerdo cuvier! Ever seen a tiger shark up close and personal? It’ll take your breath away. 10% of profits from the sale of these leggings will go to @sharktagging, helping to support research to inform management of their populations, education and outreach.
In a dense tropical forest, nearly all the visible light is captured by the overhead canopy. This is why new sun-hungry vegetation struggles to survive below, allowing for shade-loving species like moss and ferns to proliferate. When a break in the canopy does occur, such as from a fallen tree, a sprint to occupy the newly formed sunny space ensues until a new equilibrium is established.
According to Newtons 3rd Law, or for every action there is an equal and opposite reaction, Fiona and Greg will cause the Earth to move when they jump up. That’s assuming our planet is a perfectly rigid body…which it isn’t. But it’s a holiday weekend, the grill is fired up, and for the sake of this post we’re calling it rigid. If our jumpers have a mass of about 300kg, and accelerate upwards during their leap at a rate of one G, they would exert a force on the planet of about 3,000 Newtons. This means the planet moves away from them at a rate equal to 0.0000000000000000000005 meters per second squared AND if this force were constantly applied, it would take a really, really, really long time before the planet reached a walking speed. How long? You’re still reading this? Wow, we thought you’d be long gone by now. Way to hang in there! Estimates put Earth’s age at around 4.5 billion years. If you multiple that number by 14000, that’s how long it would take your legs to move the World. So in short….you don’t matter.
In color theory, the term "complimentary colors" refers to a pair of colors that when combined, cancel each other out to form a grey-scale color. In the traditional red-yellow-blue color model, these pairs are red/green, yellow/purple, and orange/blue. When our brains interpret complimentary colors, like during last night's sunset in Miami, we use different types of photoreceptor cells that balance the perception of what we see. This also results in the greatest possible contrast between colors which makes what we see seem more dramatic and attention grabbing.
Soaking in a setting sun at a hot spring in Iceland. Geothermal energy is abundant throughout the country and besides creating the best bath tubs on the planet, it is also used to generate approximately 30% of the nation's electricity and heats almost 90% of homes. Not only that, leftover warm water is circulated beneath the streets of Reykjavik to melt snow and ice, reducing the need for plows and shoveling. 📷 by Waterlust Ambassador @jmadler
We explored this cave a few years back and lost track of the photos. Hidden in the Turks & Caicos, it is a perfect natural refuge, complete with a roof and ample ventilation. The holes in the overhanging rock are examples of Karst topography, features caused by dissolution of soluble rocks such as limestone, dolomite, and gypsum. Studies have shown that people resided here long before Columbus wandered into the New World.
Will human beings endure, adapt and survive on Earth for thousands of years to come, or are we just another species with an ever looming expiration date? The answer to this question seems intimately entwined with our ability to live symbiotically with nature, including our impact on Earth's climate. Tomorrow on @natgeo, the film @fromtheashesfilm will be screened at 9/8c. We highly recommend taking a look and pondering with your friends and family about what you think the future holds? Props to Waterlust Ambassador @gibbonsphoto for the rad shot
The best diving typically happens when water is cleanest. Having good visibility, or a lack of suspended particulates or turbidity, allows you to see clearer and farther as you explore the blue abyss. A standard method to quantify water visibility is to measure how far one can see a Secchi disk, a black and white circular disc named after Italian astronomer Angelo Secchi in 1865. The maximum theoretical Secchi Depth is 70-80 meters and the maximum recorded depth is 80 meters on October 13, 1986 in the Weddell Sea, near Antarctica.
