The Lion and the Three Bulls

    THREE BULLS for a long time pastured together. A Lion lay in ambush in the hope of making them his prey, but was afraid to attack them while they kept together. Having at last by guileful [DECEPTIVE] speeches succeeded in separating them, he attacked them without fear as they fed alone, and feasted on them one by one at his own leisure.

Union is strength.

577. ANOTHER NAIL IN THE COFFIN!

Another negative event or action that contributes to one’s downfall or to something’s failure.

Global Seed Vault: the Arctic’s doomsday depository that could save plant life from climate change

Some 1,300 miles into the Arctic Circle and just 650 miles from the North Pole lies the world’s most important freezer.

Situated on Spitsbergen Island in the Svalbard archipelago, the Global Seed Vault is owned by the Norwegian government.

Contained within in it are 930,000 varieties of the world’s most precious seeds, sent by the gene banks across the globe to insure them against risks in their home country, such as natural disasters, war and looting [saccheggio].

Built to house as many as five million seed varieties, in the most extreme circumstances, the vault is intended to act as a “doomsday” [eterno] depository for global agriculture, should a major catastrophe wipe out the plants we rely on.

Three vaults lie at the end of a 130m tunnel inside the flank [fianco] of Mount Plateau, allowing the seeds to be stored deep within the Arctic permafrost. In the Vault Room the seeds are cooled to an optimal –18C.

575. MATHEMATICS: Order of Operations.

 

ORDER OF OPERATIONS

     It is very important that you carry out numerical operations in the correct order. This order is used both for positive and negative numbers.

If you do not use the correct order of operations, the answer will often be wrong!

It helps to remember   BIDMAS: 

Brackets are worked first

Indices are next

Division

Multiplication

Addition

Subtraction

EXAMPLES:

1. 3X4+5X6=12+30=42  NOT  3X4+5X6=12+5X6=17X6=103;

2. (5-12)X(4+1)= -7X5= -35;

3. (32 – 6)3 = (9-6)3 = 33 = 27.
