Answer the question at the end by quoting:

Charles Michael "Chuck" Schuldiner (May 13, 1967 - December 13, 2001) was an American singer, songwriter, and guitarist. He founded the pioneering band Death in 1983. Schuldiner is often referred to as "The Godfather of death metal", and his obituary in the January 5, 2002 issue of UK's Kerrang! magazine said that "Chuck Schuldiner was one of the most significant figures in the history of metal."
Schuldiner formed Death as Mantas in 1983 when he was just 16 years old. Original members were Schuldiner (guitar), Rick Rozz (guitar) and Kam Lee (drums and vocals). In January 1986, Schuldiner moved to Toronto and temporarily joined the Canadian band Slaughter. However, he quickly returned to continue the formation of Death.  Death underwent many lineup changes. With Chris Reifert, Schuldiner eventually released the first Death album, titled Scream Bloody Gore, in 1987. He continued with 1988's Leprosy with the line-up of former Mantas guitarist Rick Rozz and rhythm section Terry Butler on bass and Bill Andrews on drums, and 1990's Spiritual Healing, where guitarist James Murphy had replaced the fired Rozz in 1989.  After Spiritual Healing, Schuldiner stopped working with full-time band members, preferring to work with studio and live venue musicians, due to bad relationships with Death's previous rhythm section and guitarists. This earned Schuldiner something of a 'perfectionist' reputation in the metal community. Schuldiner had also fired his manager Eric Greif but settled and re-hired him before the recording of his next, influential release.  Death's breakthrough album, Human saw the band evolving to a more technical and progressive style, in which Schuldiner displayed his guitar skills more than ever. He continued in this style (and continued the success of the band) with 1993's Individual Thought Patterns, 1995's Symbolic, and finally The Sound of Perseverance in 1998. Throughout his career, Schuldiner was not afraid to take on controversial lyrical subjects, taking an anti-drug stance on "Living Monstrosity" and writing about abortion in "Altering the Future".  He put Death on hold after this to continue Control Denied, which he had been putting together prior to the release of The Sound of Perseverance, and released The Fragile Art of Existence in 1999. Control Denied also had other players from the latest Death album but featured a melodic metal vocalist. Schuldiner also played guitar in the "supergroup" Voodoocult on the album Jesus Killing Machine in 1994 and played a guest solo on Naphobia's 1995 release, Of Hell on the track "As Ancients Evolve" as a favor to the band's bassist at the time who was a friend of Schuldiner's. Schuldiner was also asked to be one of the many guest vocalists on Dave Grohl's 2001 Probot. Grohl, Napalm Death, Ozzy Osbourne, and Anthrax all increased efforts to raise funds for Schuldiner's medical bills with Grohl trying to involve Schuldiner on an album he was working on. In a 1999 interview Schuldiner spoke about why he didn't sing on the album The Fragile Art of Existence "...these vocals are all I ever wanted to do in Death but couldn't. I've had this dream of recording like that for years, and it seems like a dream come true. Tim Aymar is an amazing singer and this is the main difference. I think people will be surprised at the violence and strength of the album. Many people are expecting something like Iron Maiden, but, despite being one of my favorite bands, I didn't want to make an Iron Maiden-like album. I wanted to make an unpredictable album, just like I did in Death, I guess. I don't like to make predictable albums."

Did they release another album after that?

He continued with 1988's Leprosy

IN: Claudius Ptolemy (; Greek: Klaudios Ptolemaios, Klaudios Ptolemaios [klawdios ptoleme:os]; Latin: Claudius Ptolemaeus; c. AD 100 - c. 170) was a Greco-Roman mathematician, astronomer, geographer, astrologer, and poet of a single epigram in the Greek Anthology. He lived in the city of Alexandria in the Roman province of Egypt, wrote in Koine Greek, and held Roman citizenship. The 14th-century astronomer Theodore Meliteniotes gave his birthplace as the prominent Greek city Ptolemais Hermiou

Ptolemy's Almagest is the only surviving comprehensive ancient treatise on astronomy. Babylonian astronomers had developed arithmetical techniques for calculating astronomical phenomena; Greek astronomers such as Hipparchus had produced geometric models for calculating celestial motions. Ptolemy, however, claimed to have derived his geometrical models from selected astronomical observations by his predecessors spanning more than 800 years, though astronomers have for centuries suspected that his models' parameters were adopted independently of observations. Ptolemy presented his astronomical models in convenient tables, which could be used to compute the future or past position of the planets. The Almagest also contains a star catalogue, which is a version of a catalogue created by Hipparchus. Its list of forty-eight constellations is ancestral to the modern system of constellations, but unlike the modern system they did not cover the whole sky (only the sky Hipparchus could see). Across Europe, the Middle East and North Africa in the Medieval period, it was the authoritative text on astronomy, with its author becoming an almost mythical figure, called Ptolemy, King of Alexandria. The Almagest was preserved, like most of extant Classical Greek science, in Arabic manuscripts (hence its familiar name). Because of its reputation, it was widely sought and was translated twice into Latin in the 12th century, once in Sicily and again in Spain. Ptolemy's model, like those of his predecessors, was geocentric and was almost universally accepted until the appearance of simpler heliocentric models during the scientific revolution.  His Planetary Hypotheses went beyond the mathematical model of the Almagest to present a physical realization of the universe as a set of nested spheres, in which he used the epicycles of his planetary model to compute the dimensions of the universe. He estimated the Sun was at an average distance of 1,210 Earth radii, while the radius of the sphere of the fixed stars was 20,000 times the radius of the Earth.  Ptolemy presented a useful tool for astronomical calculations in his Handy Tables, which tabulated all the data needed to compute the positions of the Sun, Moon and planets, the rising and setting of the stars, and eclipses of the Sun and Moon. Ptolemy's Handy Tables provided the model for later astronomical tables or zijes. In the Phaseis (Risings of the Fixed Stars), Ptolemy gave a parapegma, a star calendar or almanac, based on the hands and disappearances of stars over the course of the solar year.

Was he able to predict movement of the stars
