Hey there!
Judicial review is basically the power of the courts to look at what the legislative, executive, and administrative parts do and then they determine if the acts were okay with the laws of the Constitution, or if they were against the constitutional, or unconstitutional.
Have a good day!
<u>The vacuum cleaner</u>
The firsts official vacuum cleaners were actually invented in England in 1901 by Hubert Cecil Booth. Though a great invention, his models were too big and not practical at all: they couldn't even enter buildings so it was used as a cleaning service or installed in the building itself.
After him, several other men made different versions of the vacuum cleaner: smaller, practical, portable, more efficient, with more accessories, etc. Until the American William Henry Hoover in early 1900s redesigned the vacuum cleaner: placed it in a steel box, designed attachments for the hose, added disposal filter bags and finally designed the first upright vacuum cleaner in 1926.
It wasn't until post-WW II, that the item could be afforded by American middle class and became common in households. Before it was a luxury. Later on, the appliance was widespread to the Western countries. Several variants of the vacuum have been made too.
Isn’t it like cost and demand or price and demand
Petrarch was pulled between two worlds, the ideal world of antiquity and his desire to improve the current world. He believed he could learn to make the world a better place by studying classical literature. He, along with other humanists, admired the formal beauty of classical writing. He attempted to share the teachings of classical texts by studying them, and then, imitating them in Latin writings of his own.
