The experimental verification of how light spreads at large distances - A missing experiment at foundation

We recognize that the spreading of light at large distances (the whole space) is the only property which can decide by yes or no if light really behaves physically like waves, while the fit of the waves for describing the diffraction fringes is insufficient for this purpose. Indeed, the fringe space is too limited and hence, brings the possibility of misinterpretation. Hence, the experiment for the verification if light is spreading like waves at large distances is necessary in principle, and is crucial. However, very surprisingly and tragically, this experiment was totally missing in history. This experiment uses the simplest diffraction case, in which a beam of light falls perpendicularly with its axis on the line and the plane of a straight edge. Practically, this experiment verifies if there is a dependence of the diffracted light at large distances in the geometrical shadow on the changes in beam thickness traversal to a single straight edge, while the distribution of light along the straight edge remains the same. If this dependence exists, as the wave theory for light fundamentally predicts, then the wave approach to light is physically true. If there is no dependence then light cannot behave physically like waves. This experiment can clearly be developed and performed without any calculation from the wave approach, just by a careful measurement practice. However, for a broader view, we describe in detail wave results for spreading of light at large distance, which illustrate the experiment – what are the spatial points where the measurement must be done to see if the above dependence exists, and which is the big picture for the wave approach. We attempted this experiment for many years, but could not finish it because of the lack of resources to measure at 100–500 m. The present article will empower big labs to perform this experiment. However, we show alternatively that the answer to how light spreads also comes from comparing the well known data for the diffraction on macroscopic holes with relatively recent data for the diffraction on nanoscopic holes. This comparison clearly shows that light does not spread physically like waves, which makes necessary a new, non-wave but periodic structure for light. Such an alternative answer regarding the spreading of light also makes absolutely necessary to perform the above missing experiment, as a direct way that convinces anybody how light is spreading.

Angle Trisection, Bhaskara’s Proof, and Pythagorean Theorem

This paper deals with 1) angle trisection, 2) Bhaskara’s first proof, and 3) Pythagorean theorem. The purpose of this paper is threefold. First, to show a new, direct method of trisecting the 900 angle using unmarked straight edge and compass; secondly, to show Bhaskara’s first proof of the Pythagorean theorem (c2 = a2 + b2) as embedded in this new, direct trisection of the 900 angle; lastly, to show the derivation of the Pythagorean theorem from this trisection of the 900 angle. This paper employs the direct dissection method. It concludes by presenting four points: a) the concept of trisectability as distinct from concept of constructability; b) the trisection of the 900 angle as really a new, different method; c) Bhaskara’s first proof of the Pythagorean theorem as truly embedded in this trisection of the 900 angle and; d) another way of deriving Pythagorean theorem from this trisection of the 900 angle.

Alignment Methods in Rotating Equipment

This research provides an analysis about the need to implement innovative alignment techniques and to diversify the methods to carry it out, if there is outdated equipment, misalignment becomes more recurrent and this causes the equipment to present failures as high vibration, high temperature, product leaks, excessive energy consumption and wear of some equipment components. In turn, this text exposes the methodologies of alignment of axes by straight edge, dial indicator, and by laser alignment, and makes a comparison of the advantages and disadvantages between these three methods to conclude which of them brings greater benefits to the industry today.

I want something new: Limp Records and the birth of DC punk, 1976‐80

Recountings of the Washington, DC punk rock scene’s history often start with the founding of Dischord Records in 1980 and focus on the subsequent ascent of Dischord co-owner Ian MacKaye’s bands like Minor Threat and Fugazi. As seminal as Dischord remains in the narrative of DC punk ‐ a community still thriving today ‐ the years just prior to the label’s founding generated the scene’s true incunabula. Beginning with the self-released debut EP from the Slickee Boys in 1976, this first wave of DC bands ‐ also including Razz, Nurses, White Boy and others ‐ combined elements of art rock, surf, proto-punk, pub rock and power pop together to craft a protean version of punk that embraced eccentricity and humour, serving as the city’s own defiant rebuke of the staid state of 1970s rock music. No record label was more central to the nascent punk scene in DC than Limp Records. Operated by Skip Groff, Limp provided the punk community with its first proper record label. Rather than a label that centred around the efforts of a single band ‐ as most other new DC punk labels did ‐ Limp issued singles for several groups, collaborating with the fledgling Dacoit and O’Rourke labels to co-release defining singles for the Slickee Boys and Razz. DC punk would not have taken shape the way it did without Groff’s efforts, particularly considering his connections with bands like Bad Brains and the Slickee Boys and his musical and entrepreneurial influence on local teenage punks like MacKaye, Jeff Nelson and Henry Rollins. This article is a history of DC punk record labels from 1976 to 1980 and seeks to establish this overshadowed era of the scene as one of the most critical in the community’s 43-year existence. Considering the outsize influence the DC scene ultimately had on punk culture ‐ whether through the eponymous clean living philosophy inspired by the Minor Threat song ‘Straight Edge’, the unwaveringly independent business model of Dischord or the pacesetting music reliably turned out each decade by participants in the scene ‐ the impact of Groff and his first wave DC punk peers must be acknowledged.
