Biography

To my mind Slipher doesn't get enough credit, obviously was influenced heavily by Lowell, but his observations were his own. The biggest reason why he didn't get the fame others have is because he was super humble and didn't publish his works in major journals. I took an interest in him since reading about the early evidence for the Big Bang since his work became the basis for measuring the speed of the expansion of the universe. The best biographical work I could find was this ^[1], particularly:

In 1929 Hubble derived his important velocity-distancerelationship for nebulae using, as he later wrote Slipher,"your velocities and my distances."120 Hubble acknowledgedSlipher's seminal contribution to his own work by declaringthat "the first steps in a new field are the most difficult andthe most significant. Once the barrier is forced, further de-velopment is relatively simple."121

And for actually understanding his work, this presentation ^[2] refer images therein. I think it would be worth trying to pull this together succinctly. Linden (talk) 11:21, 4 July 2021 (UTC)[reply]

I'm going to be adding a personal life section and reorganizing some of what is already here. Gac8cx (talk) 16:15, 7 April 2023 (UTC)[reply]

Extraneous information

The following should be removed as it is not about Vesto Slipher. I understand it is a reference to the impact of his work but that is made implicit by the linking in the previous paragraph.

"Earlier, in 1917, Albert Einstein had found that his newly developed General Theory of Relativity indicated that the universe must be either expanding or contracting. Unable to believe what his own equations were telling him, Einstein introduced a cosmological constant (a "fudge factor") to the equations to avoid this "problem". When Einstein heard of Hubble's discovery, he said that changing his equations was "the biggest blunder of my life".[4]" Miglewis (talk) 13:05, 8 September 2008 (UTC)[reply]

Name

It is not clear to me which language the name "Slipher" is in and how he pronounced it. —Preceding unsigned comment added by 86.160.202.155 (talk) 09:01, 24 September 2008 (UTC)[reply]

It might be Skandanavian. —Preceding unsigned comment added by 86.160.202.155 (talk) 09:57, 24 September 2008 (UTC)[reply]

As a Indiana University graduate, the name is pronounced Sly-fur among those I've spoken to in the Astronomy department.Miglewis (talk) 17:21, 10 October 2008 (UTC)[reply]

Cosmological redshift - question

Are the redshifts discovered by Slipher of cosmological significiance? The galaxies close from the Milky Way are not receeding. Even velocities of close receeding galaxies are still out of the distance-redshift relation. Does Slipher mesured the redshifts of galaxies at more than a few Mpc?

Specifics Regarding Spiral Nebulae Research

In a book titled Hutchinson Trends in Science - Astronomy by Helicon Publishing, they mention some specific techniques in which Slipher discovers this movement. I added this in where it is discussed. Peeparoni (talk) 17:33, 3 March 2023 (UTC)[reply]

Additions to Discoveries

I found in a detailed history book over astronomy and astrophysics a lot of references to the specifics of Slipher's work.^[1] I will begin to add these discoveries into the Discoveries section. Peeparoni (talk) 20:26, 7 April 2023 (UTC)[reply]
