and was safer to use.

Now, we can turn on a light whenever we need it—
whether it’s day or night! The light bulb helped make
homes brighter and workplaces safer.

over long distances. Before phones, people could
only communicate face-to-face or by writing letters.

It made it possible to call anyone from anywhere in
the world! We now use phones for talking, texting,
and even video chatting!
