Science Quotes by Gabriel Fahrenheit (4 quotes)

I read … that the celebrated Amontons, using a thermometer of his own invention, had discovered that water boils at a fixed degree of heat. I was at once inflamed with a great desire to make for myself a thermometer of the same sort, so that I might with my own eyes perceive this beautiful phenomenon of nature.
— Gabriel Fahrenheit
From 'Experimenta circa gradum caloris liquorum nonnullorum ebullientium instituta', Philosophical Transactions (1724), 33, 1, as translated in William Francis Magie, A Source Book in Physics (1935), 131.
Science quotes on:  |  Guillaume Amontons (3)  |  Beautiful (271)  |  Boil (24)  |  Celebrate (21)  |  Degree (277)  |  Desire (212)  |  Discover (571)  |  Eye (440)  |  Fixed (17)  |  Great (1610)  |  Heat (180)  |  Inflame (2)  |  Invention (400)  |  Myself (211)  |  Nature (2017)  |  Perceive (46)  |  Phenomenon (334)  |  Read (308)  |  Thermometer (11)  |  Water (503)

It then came into my mind what that most careful observer of natural phenomena [Amontons] had written about the correction of the barometer; for he had observed that the height of the column of mercury in the barometer was a little (though sensibly enough) altered by the varying temperature of the mercury. From this I gathered that a thermometer might be perhaps constructed with mercury.

From 'Experimenta circa gradum caloris liquorum nonnullorum ebullientium instituta', Philosophical Transactions (1724), 33, 1, as translated in William Francis Magie, A Source Book in Physics (1935), 131.
Science quotes on:  |  Alter (64)  |  Altered (32)  |  Guillaume Amontons (3)  |  Barometer (7)  |  Careful (28)  |  Column (15)  |  Construct (129)  |  Correction (42)  |  Enough (341)  |  Gather (76)  |  Height (33)  |  Invention (400)  |  Little (717)  |  Mercury (54)  |  Mind (1377)  |  Most (1728)  |  Natural (810)  |  Observe (179)  |  Observed (149)  |  Observer (48)  |  Phenomenon (334)  |  Temperature (82)  |  Thermometer (11)  |  Vary (27)

The degree 48 … in my thermometers holds the middle between between the limit of the most intense cold obtained artificially in a mixture of water, of ice and of sal-ammoniac or even of sea-salt, and the limit of heat which is found in the blood of a healthy man.
— Gabriel Fahrenheit
From 'Experimenta circa gradum caloris liquorum nonnullorum ebullientium instituta', Philosophical Transactions (1724), 33, 1, as translated in William Francis Magie, A Source Book in Physics (1935), 131. Hence, Fahrenheit specified the upper and lower fixed points of his temperature scale, ranging from 0 to 96.
Science quotes on:  |  Artificial (38)  |  Blood (144)  |  Cold (115)  |  Degree (277)  |  Healthy (70)  |  Heat (180)  |  Ice (58)  |  Intense (22)  |  Limit (294)  |  Man (2252)  |  Mixture (44)  |  Most (1728)  |  Obtain (164)  |  Sal Ammoniac (2)  |  Salt (48)  |  Sea (326)  |  Thermometer (11)  |  Water (503)

When a [mercury] thermometer … was made (perhaps imperfect in many ways) the result answered to my prayer; and with great pleasure of mind I observed the truth [that water boils at a fixed degree of heat].

Carl Sagan Thumbnail In science it often happens that scientists say, 'You know that's a really good argument; my position is mistaken,' and then they would actually change their minds and you never hear that old view from them again. They really do it. It doesn't happen as often as it should, because scientists are human and change is sometimes painful. But it happens every day. I cannot recall the last time something like that happened in politics or religion. (1987) -- Carl Sagan
