I like that I can quickly sign something without printing and scanning signing and scanning again. I can send this out right from here via my email, haven't checked Gmail records yet, but if they've been recorded there, I think I will use this app for years to come.

I find it very helpful, but sometimes I can't find the form I have completed and I have to start over when I need to make changes. Or it wont allow me to make changes.

Very easy to use!!
Walks you through as you are filling out. Very helpful for first time user. Easy to go back to make corrections. I work in the dental field and our software does not convert to medical, so this software made it easy for me to use.

Kara, The Support Agent
The Support Agent, Kara, that helped me with what I wanted to do was very accommodating and friendly. I had not fully explored the features of this application but I needed to get something rather urgently. Kara was very patient in explaining to me all that I needed to do. I am quite impressed with the Support provided by Kara and by PDFFiller itself.

How was the concept of time created?
A large variety of devices have been invented to measure time. The position of the shadow marks the hour in local time. The idea to separate the day into smaller parts is credited to Egyptians because of their sundials, which operated on a duodecimal system.
How was time created?
A large variety of devices have been invented to measure time. The study of these devices is called horology. The position of the shadow marks the hour in local time. The idea to separate the day into smaller parts is credited to Egyptians because of their sundials, which operated on a duodecimal system.
Who created the concept of time?
Hipparchus, whose work primarily took place between 147 and 127 B.C., proposed dividing the day into 24 equinoctial hours, based on the 12 hours of daylight and 12 hours of darkness observed on equinox days. Despite this suggestion, laypeople continued to use seasonally varying hours for many centuries.
Who invented hours and minutes?
THE DIVISION of the hour into 60 minutes and of the minute into 60 seconds comes from the Babylonians who used a sexagesimal (counting in 60s) system for mathematics and astronomy. They derived their number system from the Sumerians who were using it as early as 3500 BC.
How did they tell the time in the olden days?
The sundial is looked on as being a form of sun-powered clock. This shadow clock or sundial permitted one to measure the passage of hours within a day. Another very early form of clock to tell the time was the water clock. The water clock was used by the ancient Greeks.
What is the concept of time?
The concept of time is self-evident. An hour consists of a certain number of minutes, a day of hours and a year of days. Time is represented through change, such as the circular motion of the moon around Earth. The passing of time is indeed closely connected to the concept of space.
Is time an illusion?
According to theoretical physicist Carlo Novella, time is an illusion: our naive perception of its flow doesn't correspond to physical reality. Indeed, as Novella argues in The Order of Time, much more is illusory, including Isaac Newton's picture of a universally ticking clock.
What is theory of time?
The B-theory of time is the name given to one of two positions regarding philosophy of time. B-theorists argue that the flow of time is an illusion, that the past, present, and future are equally real, and that time is senseless. B-theory is often drawn upon in theoretical physics, and in theories such as eternal ism.
