Let's Learn About Rabbits vs Hares

Rabbits are clearly distinguished from hares in that rabbits are altricial, having young that are born blind and hairless. In contrast, hares are generally born with hair and are able to see (precocial). All rabbits except cottontail rabbits live underground in burrows or warrens, while hares live in simple nests above the ground (as do cottontail rabbits), and usually do not live in groups. Hares are generally larger than rabbits, with longer ears, and have black markings on their fur. Hares have not been domesticated, while European rabbits are often kept as house pets. In gardens, they are typically kept in hutches — small, wooden, house-like boxes — that protect the rabbits from the environment and predators.

Let's Learn About the Classical Languages

The Classical languages of the Ancient Mediterranean world influenced every European language, imparting to each a learned vocabulary of international application. Thus, Latin grew from a highly developed cultural product of the Golden and Silver eras of Latin literature to become the international lingua franca in matters diplomatic, scientific, philosophic and religious, until the seventeenth century. In turn, the Classical languages continued, Latin evolved into the Romance languages and Ancient Greek into Modern Greek and its dialects. Moreover, it is in the specialised science and technology vocabularies that the Latin influence in English and the Greek influence in English are notable, however, it is Ecclesiastical Latin, the Roman Catholic Church’s official tongue, that remains a living legacy of the classical world to the contemporary world.

Let's Learn About Concrete

When one thinks of concrete, the image of a dull, gray concrete wall often comes to mind. With the use of form liner, concrete can be cast and molded into different textures and used for decorative concrete applications. Sound/retaining walls, bridges, office buildings and more serve as the optimal canvases for concrete art. For example, the Pima Freeway/Loop 101 retaining and sound walls in Scottsdale, Arizona, feature desert flora and fauna, a 67-foot (20 m) lizard and 40-foot (12 m) cacti along the 8-mile (13 km) stretch. The project, titled "The Path Most Traveled," is one example of how concrete can be shaped using elastomeric form liner.

Let's Learn About the Tasmanian Devil

The Tasmanian devil (Sarcophilus harrisii) is a carnivorous marsupial of the family Dasyuridae now found in the wild only in the Australian island state of Tasmania. The size of a small dog, it became the largest carnivorous marsupial in the world following the extinction of the thylacine in 1936. It is characterised by its stocky and muscular build, black fur, pungent odour, extremely loud and disturbing screech, keen sense of smell, and ferocity when feeding. The Tasmanian devil's large head and neck allow it to generate the strongest bite per unit body mass of any living mammal, and it hunts prey and scavenges carrion as well as eating household products if humans are living nearby. Although it is usually solitary, it sometimes eats with other devils and defecates in a communal location. Unlike most other dasyurids, the devil is able to thermoregulate effectively and is active during the middle of the day without overheating. Despite its rotund appearance, the devil is capable of surprising speed and endurance, and can climb trees and swim across rivers.

Let's Learn About Macadamia Nuts

The macadamia nut has an extremely hard shell, but can be cracked using a blunt instrument, such as a hammer or rock applied with some force to the nut sitting in a concave surface, or a custom made macadamia nutcracker can be used. Macadamia nuts are often fed to Hyacinth Macaws in captivity. These large parrots are one of the few animals, aside from humans, capable of cracking and shelling the nut. Nuts of the "Arkin Papershell" variety crack open more readily.

Let's Learn About Iron Use Before the Iron Age

Meteoric iron, or iron-nickel alloy, was used by various ancient peoples thousands of years before the Iron Age. This iron, being in its native metallic state, required no smelting of ores. By the Middle Bronze Age, increasing numbers of smelted iron objects (distinguishable from meteoric iron by the lack of nickel in the product) appeared throughout Anatolia, Mesopotamia, the Indian subcontinent, the Levant, the Mediterranean, and Egypt. The earliest systematic production and use of iron implements originates in Anatolia, beginning around 2000 BCE. Recent archaeological research in the Ganges Valley, India showed early iron working by 1800 BC. However, this metal was expensive, perhaps because of the technical processes required to make steel, the most useful iron product. It is attested in both documents and in archaeological contexts as a substance used in high value items such as jewelry.

Let's Learn About the Pangolin

Pangolins lack teeth and the ability to chew. Instead, they tear open anthills or termite mounds with their powerful front claws and probe deep into them with their very long tongues. Pangolins have glands in their chests to lubricate the tongue with sticky, ant-catching saliva.
