Stone age .
The stone age was a long time ago . https://www.youtube.com/watch?v=0u8bDJD5x1g. <Watch this! The Palaeolithic was the first part of time in the stone age . The Mesolithic is the middle part of the stone age . The Neolithic , well you guessed it , the new part of the stone age .
Albert Einstein: A Genius from ULM, Germany 14 /03 / 1879-18/04/1955
During his early years, Einstein’s learning abilities raised concerns for his parents. Until the age of five, he struggled to construct full sentences, prompting worries about his intellectual development. However, his innate fascination with the world and the inner workings of things was evident from a young age.
At the age of five, a pivotal event occurred when his father gave him a compass to play with. This seemingly simple object captivated young Einstein, particularly the consistent pointing of the needle towards the earth’s magnetic north. Reflecting on this experience later in his autobiography, Einstein revealed that his curiosity about the compass sparked thoughts about unseen forces at play in the world. Later Albert was a total genius because, he had read a neighbor’s high school book and knew about squares. Despite the hard journey, Albert Einstein made it extremely easier for the world . He was a physicist who published a theory of special relativity . E=mc square and formulating the photoelectric laws and left the whole world shocked . If you think this is the smartest person, Meet William James Sidis the Total genius!
Science
Magnets
Magnets are devises that join metal with it . Gold can’t attract with magnets but iron can . Attract is a pull force , but repel is a push force that pushes the material away . There are some materials that are not magnetic for example Gold , Zinc , Silver , copper and aluminum. Magnetic materials at the other hand are different , there are only 3 magnetic materials that are Iron, Nickel and cobalt . Your fridge is magnetic too ! Try doing an experiment , use a magnet to pick up things that are magnetic in your house for example your fridge , doorknob et cetera . There are some objects that are not magnetic some of them are a pen (not made of iron nickel or cobalt ,a plastic one .),Gold doorknob and more . If you connect a magnet with another magnet , please don’t try and put the south with south in the magnets , because the souths are friends with each-other ! If you had a big heavy load … Use an electro -magnet if it is made of iron , Nickel or cobalt ! If it is not too heavy , use a horse-shoe magnet . If it’s not at all heavy , use a bar magnet . If it weighs like a paper clip… Use a ring magnet (Neodymium magnet Nib)
Quiz Time!
If I had a piece of zinc and tried to make a magnet to it … Would it even work ? go on the notification bell to tell me ! There is a link to the comments from me!
Electricity .
Electricity normally goes in magnets . The button gives a wire to connect the energy to the wires already there . The circuit gets the energy to flow and the magnets push each other .
